Update 01.136 - Bug Fixes and Improvements

In this week's update, we're bringing you lots of bug fixes and improvements. The biggest fix is for ship toolbars - they're now synchronized between the server and the clients, so you'll no longer lose your configurations when you rejoin a server. Also, you will correctly see any modifications made to a toolbar by other players.
We've also improved the 3rd person camera, which now acts differently based on whether you are in a ship or station control seat. Because of these changes, the 3rd person camera should now be much easier to control. It's also easier to merge stations when using copy and paste. A number of issues that caused crashes have been resolved, and we fixed character animations being out of sync on multiplayer servers.

Update 01.135 - Bug Fixes and Improvements

This week's update brings you several improvements for modders that we've merged from our community on GitHub, plus more bugfixes. From Tyrsis we have production API changes and terminal changes, so modders can now create their own terminal interfaces such as buttons, sliders, etc. Another addition is Malware's Ship Data update and remote control fixes that makes Coop mode work when a conveyor block (or any block that doesn't have an owner) is between the master and slave assemblers. And last but not least, we have Rexxar's projector ModAPI changes which have added more ModAPI interface to the projection API.
Our GitHub source code has also been updated.
Many thanks to our entire community for helping us develop the game and raise the bar for modding possibilities. We're simply in awe of all the mods and creations you guys publish on the Workshop :)

About This Game

Space Engineers is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.

Space Engineers features a realistic, volumetric-based physics engine: everything in the game can be assembled, disassembled, damaged and destroyed. The game can be played either in single or multiplayer modes.

Volumetric objects are structures composed from block-like modules interlocked in a grid. Volumetric objects behave like real physical objects with mass, inertia and velocity. Individual modules have real volume and storage capacity.

Space Engineers is inspired by reality and by how things work. Think about modern-day NASA technology extrapolated 60 years into the future. Space Engineers strives to follow the laws of physics and doesn't use technologies that wouldn't be feasible in the near future.

Space Engineers concentrates on construction and exploration aspects, but can be played as a survival shooter as well. We expect players will avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications to survive in space and on planets. Space Engineers shouldn’t be about troops; it should be about the machinery you build.

    - Empty World – no asteroids, no ships; suitable for creative mode
  • Enemy NPCs
    - sabiroids (spiders): can be found on alien planets and on Titan moons. They can destroy metal blocks and attack players. Their favorite hunting strategy is hiding in the ground and un-burrow to surprise their prey. When players kill a spider, new spiders won’t appear in the area for some time. They also store some components inside their bodies from objects and blocks that they consumed.
    - pirate bases: can be found either in space or occupying planetary surface. They have bounty hidden inside their containers that players can loot if they get over the drone attacks.
    - enemy drones: they spawn automatically from pirate bases and attack the players when they venture into pirate territory
  • Ships (small and large ships – build them, pilot them and crush them
  • Space stations
  • First-person & Third-person
  • Planetary bases, outposts, cities!
  • Dedicated servers - allow players to connect to a third party host, rather than using a player-host, in a peer-to-peer set-up. The result is a faster connection and a more fluent multiplayer performance with less lag

  • Large weapons - missile launcher (for large ships)
  • Jump drive – a traveling mechanism that allows players to travel big distances in a short period of time
  • Solar panels - produce energy depending on the amount of light that they catch from the sun
  • World management – generate new worlds, “save as” to multiple copies, auto-save every 5 minutes (can be turned on/off), edit world settings

  • Conveyor, Collector, Connector (IMPORTANT: this is a first work-in-progress version and a realistic version will be added later) - Conveyors move items from inventory to inventory. Collectors can collect small objects (ore, ingots, components, tools) into inventory. Connectors can throw items from inventory to space (in future update could be used to connect two ships/stations and transfer items)
  • Artificial mass – can be used to add gravity-affected mass to ships, useful in machine ships or cars
  • Wheels - use them with rotors and artificial mass to build vehicles
  • Automated turrets – gatling, missile and interior. Turrets are used mostly as defense mechanism rather than shooting other players. They aim on decoys (automatically by default), meteorites, missiles or all moving objects (eg. small/large ships) - targeting can be changed in the control panel

I have thus far put several hundred hours into space engineers, and have owned the game for over ayear now.
There are a lot of things going for this game, from having a fairly capable graphics engine, to providing hours of creative play.

However, whenever I launch the game it's a bit of a gamble. Sometimes it launches, other times it crashes, other times it BSOD my machine. Despite patches that come in on a weekly basis, little has been done to help ensure that the game will actually be able to get past the main menu. I cannot recomend the game at all at this point, as it's gone well beyond annoying to stealing the fun out of the game; I no longer want to gamble trying to run this game and have moved on to other titles.

This game used to be in my favorites, then the developers discontinued the Direct x 9 branch which was all I could run on my ♥♥♥♥♥♥ laptop.

Now it sits with the rest of my games, right between Sims 3 and Space Run

Still got 386 hours out of it before that happened, so 9/11

It's a great game but buggy as ♥♥♥♥. The devs need to spend a year on fixing bugs and other problems before they add any more features.

I've had more fun with this game than any other in years, but in the past 2 days I've run into 15+ separate bug issues and eventually gotten fed up with it.

Thumbs up because I had a lot of fun, but serious caution advised.

Limited edition. Like forever and quite limited.
Promising ideas at start turned into seemingly endless & almost useless update story. Too much sand in this sandbox.

Great community creating and doing incredible things, even repairing bugs themselves but this project is now almost 3 years old and despite weekly updates it still feels like probably 1 year old. Some things are too booring, predefined and after all this time - poor. Some break the whole time. Ingame coding part limited in access to many important parameters/commands. Multiplayer progressively losing simspeeds. Battles lame. Planetary aircraft incapable of aerodynamics without a mod. Planets themselves too synthetic and useless. "Painted" Sun on background circling planets. Iron, Cobalt, Nickel,.. Gold, Platinum yet no Copper. Do they really use silver wires? :)
Main reason? There are just better games out there. Kerbal for space tinkerers, other for battle oriented.

Still a nice try. Would have recommended 2 years ago. Not anymore.

Early access. ETA 2021+

If you enjoy a sandbox and space you will likely enjoy this game. Does it have bugs yes. Is it early access yes so you should expect bugs. I have been a game tester for Bethesda, Bungie, Gear Box, and several other game companies. I don't go out preaching how to make a game. This game is fun currently. If your expecting massive space battles, your dilusional. It is not desgined or set up for that. It currently set up for a few friends to do stuff together or play by yourself. Not saying it won't ever be a mega massive space battle game but it currently is not. SO if you want big missive space battles keep watching this game till it is finished and when it is finished see if it has become what you wanted. Do not buy it than cry about how it isn't what you dreamed.

I never write reviews but I feel like KSH has lost their way again and are gonna drive this almost perfect game concept into the ground like they did to Miner Wars. It's a shame that after over 1500 hours in game, I have to shelf my favorite game due to bugs. The devs seem totally clueless as to how to fix the game too as every patch makes it worse and less playable. I've built bases, ships of all sizes, mechs, wheeled vehicles, satellite arrays etc, etc but none of it ever gets used cuz there is nothing to really do in the game. The "pirates" are a joke and the cyber hounds was Keen's way of trolling us for all the harsh criticism, I guess. I really miss the days when I could actually do things with my creations. Now mp is broken af and sp is a glitchy mess. Some optimization is noticeable but after almost three years of development the game looks further from completion than ever. Kudos to the dude that made the Trump ship with the caption "make space engineers great again" lmao...


I realized my comment above is not a review and more of a rant so here's a review from a veteran space engineer. Warning: I could write a book about this game lol.

Alone on a desolate planet or out in space, the player assumes the role of some kind of demi God or android able to mine and refine raw materials to use in the building of evermore elaborate machines for the purpose of exploring the cosmos and surviving it's dangers.
Features like terrain deformation, a robust building mechanic and a fun physics engine are the highlights of this gem. However, if you're hoping to get out there as a novice and conquer the universe, I'd better warn you: IT'S NOT EASY MAN. The learning curve is steep as can be since the tutorials are garbage and the UI is a nightmare. But after graduating from the school of hardknocks, a masters from YouTube university and some trial and error, things can be built.
Time to get creative because it's up to you to figure out from where or how the fun is extracted from this title. It MUST be mentioned that the awesome player community by itself almost makes the game worth buying and is a huge source of fun. With that said, the workshop is your friend, just stay away from mp for now. Trust me.
Build a miner ship to dig up ore but it's more trouble than its worth since you can just spawn everything you need for free and there is no persistent story world to make you care about it so unless you're really into drilling for the fun of it... Build a fleet but you're the only one around so...
Build a base but you're the only one around so...
Build a massive interplanetary communication satellite array to talk to yourself... (although cameras on satellites is a joy like no other)
Build wheeled vehicles that would never pass a road test on earth much less on rough alien terrain. To be fair though, I do have some wheeled vehicles that are quite usable and I even tow trailers loaded with stuff with very mixed results. But you're the only one around so...
Spend hours building a murder ship only to get murdered by your own base defences during its first test flight.
Build a mech that really works till the next update wrecks everything you thought you knew about gravity and turns your mech into another check in the fail column.
The most actual fun I've had here is being a pirate. I raid any bases or ships passing by in space and the in game pirate drones act like the police in my case and try to stop me. They in turn get rekt and looted (a gatling gun, a camera, some skill and you're a killing machine). I usually make it home in one piece but since survival mode isn't very good atm, looting is just for fun.
The universe is procedurally generated and rendered beautifully but the game is clearly geared toward building since there is no map, radar, story, npcs or end goals although there is stuff to find out there like ships, bases and hostile drones but they are far and few in between. Also, there is a very crude fps element to the game that is better left unspoken. It's an early access title after all.
My advice is wait til this game gains some weight and focuses on what's important or play it in creative mode, learn the ropes, build your heart out and blueprint everything. Some must have mods make the game a lot more enjoyable but any update can break their functionality so keep that in mind.
Get familiar with some of the dev tools provided like space master, voxel hands and spectator mode and the game will open up to you. Otherwise, save up for some of the more approachable space sim/ builder games out there.
If this review seemed too long or complicated then this game is definitely not for you.
It's heart breaking to see that the super complex options and block functions get blamed for the poor performance and dev difficulty but this is why Space Engineers is so great. I fear that future devs will seek to "improve" this concept by simplifying and that's sad indeed. In a perfect world, a full space sim would be a blend of SE and other, more story rich titles like Star Citizen. You gotta at least give Keen credit for trying to tackle this giant by developing a whole engine for it. But that's just my opinion. I state it to point out that the lack of "meat and potatoes" could be this title's undoing, not complexity. I can't imagine any casual gamer bearing through the grind for so little reward though.
I usually play in survival with very few mods, cyber mutts off and space master on for fun and sometimes play creative mode to build freely. The possibilities are endless but the twisted, explosive will of clang always looms just a connector coupling away...

7/10 Although I wouldn't recommend, I would be disappointed by dizzy devs again and again and again

Been putting this off for a while now, but due to recent spates of negative reviews i think it would be a good idea to make one, if only to make people more aware.

First off before the actual review i will write a warning to newer players.

This game is unfinished, do not judge it based on its current bugs as they are being fixed.

People who claim that development is taking too long need to realize that this was being developed by a very small dev team for quite some time until relatively recently (and a good portion of the current dev team is fairly new to game development), that they are working on two games at once (medieval engineers), and that they used better part of a year developing planets at the demands of the community (which a few members of the long term community think was a mistake. That is open to speculation). In other words, cut them some slack.

This game is EXTREMELY GPU and RAM intensive, i do not suggest running it with less than 8gbs, (16 recommended). Also bear in mind that some planets will refuse to load on low end GPUs and that others will run badly. For example you will run Mars at 30 odd fps on a GTX 750ti, 50-60 on a 980. Earth and the alien planet will run at 50-60 fps on a GTX 980ti (basically a titan x with less vram). I also hear that AMD cards and CPUs run worse than their Intel and Nvidia counterparts, though this is inconsitant.

As such i STRONGLY suggest you stay away from planets if you have a weaker GPU, i can manage 40fps on intel integrated graphics in space.

Multiplayer is currently broken, though new netcode is on the way and indications are that it is nearly complete. Stay away from dedicated servers until it drops, private games with 2-6 people run perfectly fine for the most part, though i do not recommend using pistons and rotors, they will invoke to wrath of Clang (the patron god of Space engineers and utter ruin).

That just about covers it for the warning, i will add more as i either remember things or otherwise find out more.


Now, for the actual review.

Space engineers is a semi realistic sci-fact voxel based building and exploration game (emphasis on the building part).
In this game you will build, mine and fight pirates (single player) and other players (multiplayer) in the hope of creating massive battleships to oppress the peasants, and defend what you own.

You can build basically any ship from movies, other games and TV series, or something original (but mostly you will end up building flying bricks due to your lack of aesthetic skill), the only limits are your imagination, and your computer.

Mining for resources is actually very fun in this game due to deformable terrain.

The fighting part could use a little work, but it does the job fine for the moment.

The exploration element is similar (if not somewhat superior) to that found in Elite: Dangerous, difference being the main reasons are to find a nice looking place for a base, look for resources, or if you have both, look for the community made ships that are placed extremely infrequently across the galaxy. Rather than just to have your name on a planet, though you can do that too if you really want.

The UI is, to be honest a little daunting at first, but it does the job.

The graphics are some of the best in the genre, and the models and effects are currantly being improved.

The music is decent (love the title screen song), but after a while you get a little tired of it.

The modding community is absolutely fantastic, on par if not better than the Skyrim one.

Infact the community in general is superb for the most part. Probably the best i have found yet.

The game is updated every week on thursday, and hotfixes released as soon as they are finished.

Youtubers for this game in general are great, i suggest VideoSage, XP gamers and W4stedspace.

That about covers it for the review.

TL;DR To me this game is fantastic and has the potential to be even better, and it looks like the devs are going to deliver.


Edit: Before putting a dislike in, make a comment so I know what you disagree on and how i can help fix it.

Space Engineers is a very promising, inspiring and creative game. If you like playing alone in an empty universe, then you must definitely try this game. You won't regret it. It is one of the best single-player sandbox games I have ever played.

Everything is great until you try the multiplayer.
Extremely unstable, insanely laggy, frustratingly buggy.

No, it's not my internet connection (I have a very fast connection) and no, it's not my pc (I have a very high end pc).
It's just that the game is severely unoptimized. Whenever I join an online server, the game switches to s**t mode.

There are so many things not working in multiplayer that I can't possibly list them here, some of which are:

- Lag gets so extreme that you must wait for 30 seconds for even the most simple action
- Game freezes for 10 - 20 seconds for no apparent reason
- Player jumping all over the place, without any chance of controlling it
- Lag stuttering gets so intense that can give you a seizure
- On planets, player suddenly starts sinking into the ground, free falling to the center of the planet and ultimately dying
- Sudden death for completely inexplicable reasons
- Parked vehicles explode for no reason
- Stationed ships explode for no reason
- Drills and rotors explode for no reason
- Merge blocks explode for no reason
- Parked vehicles jumping all over the place for no reason
- Stationed ships jumping all over the place for no reason

You get the idea.

Overall, great for single-player, unplayable in multiplayer.
Yes, it is in early access but there are serious bugs that remain unsolved for 2 years and I don't think they will be ever solved.

Looks like this game suffers from the eternal-early-access syndrome, which is very common these days.

I miss the times where servers weren't speed capped at 50 m/s.

The times where you could actually move around normally without your character taking off into the sky when you move your mouse around with high sensitivity..

Something went wrong, really, really wrong. I don't know how or what it has been caused by but damn, do I miss the old game.. It makes me cry deep inside of me whenever I try to play on a server, it's like trying to get into something again but then it just scrubs you in the face with a metal brush.

And the times where multiplayer.. ughh nevermind, I bet most of you guys weren't playing the game from the start, so you don't know how I feel like about Space Engineers right now, the optimizations destroy the game rather than make it better, I remember a few patches back multiplayer was actually stable, but now it's A LOT worse.

New ships sounds don't really fit in, and they're skimmed off Elite: Dangerous, doesn't really feel as fast as it sounds like with only 50 m/s speed caps on the servers..

Only get this game if it's on ULTRA discount, unless you don't care about multiplayer.

Singleplayer runs pretty well, multiplayer is hell and WILL make you MAD many, many times.

Graphics are very nice, it's just the optimization part, playing on dedicated servers makes you rather want to walk on a contraband in real life than watch it happen in-game.

Alright so due to a recent impulse of negative reviews I want to clear up a few things about SE.
ONE, it is in (Beta), and has one of the most active development base in all of steam and early access.
Also, the main features have been added, and optimization is the next step, the game has gotten SO MUCH BETTER since it
first came out, and people complain about the performance after the planetary release, this was a huge feature.
The game uses a lot of computing for mapping out and modifing a massive planet, so there is a pretty big load on your
PROCESSORS, this game doesn't need a badass GPU, it needs a pretty good CPU to run smoothly. The Network coding is being completely restructured, so obviously it is going to take awhile to be sufficent, but it WILL be better than it was before. All in all, this is a great creative game that is great for you if you have a good rig and love other creative survival games like Rust, Minecraft, DayZ, H1Z1, etc.

Ok, i have been playing this game for a while now and i think its time to write a review.

+ great potential
+ lots of things to do
+ SP
+ Great non-toxic community
+ Capital ship battles with my friends
+ update videos, dancing dusan(music video coming soon maybe?).
+ Community plays a huge part in the design of the game.

- Bugs, lots of them
- MP sucks, (netcode improvements are coming tho.)
- optimization (working on it tho)
- Crashes
- rotors, pistons and all things CLANG.

In general i would recommend this game to anyone who has creativity and likes Space. The community is great and the devs bring out lots of teasers and information about development, its even possible to chat with some of the devs on xocliw's (community manager) stream or on discord.

Not playable in it's current state. Devs need to reconsider the number of features and the overall method of networking and game functionality. It might be decent in a year or so, but we said this a year or so ago.

This game is very fun when it's working as intended, but i can't recommend it for people who want to play it with their friends, which was the main draw for me. The game seems to be a much less bug-ridden experience if you play solo and perhaps in a creative mode, but networked and survival gameplay is very much unpolished.

I've owned this game for years now and i've played it at multiple stages during it's development, which makes me feel like i have a decent grasp on it's issues with it's rate of development and bugfixing, which motivated me to write this review.

I had a lot of fun with this game. I've played it for near 100 hours. After KSP it's probably the best space sandbox game.
But despite all of it's potential i can't really recommend the game, especially as a person who likes multiplayer and playing with friends.

I've always thought that this game was great, but after having it for years i'm not seeing much improvement in terms of bugfixing and networking optimization.
If you want to buy this game, even despite all the bugs, in hopes that the developers will fix it.. I'm saying, don't do it. There is no guarantee that they'll fix anything, since they haven't really fixed any of the core networking issues since i first played the game. Everything is still jumpy, permanently desyncing, crahsing, etc.

The game is ridden with bugs that can break your server unless you clean it up occasionally.
It's also full of bugs that have you or your buddies constantly restarting the game.
Most of the game's issues are networking-related, for example clients not receiving the same information, even at <100 ping, which spirals out of control for some reason, ending at a point where clients may not see interactions of some objects at all, or they see everything 10km away from where it really is. These are really common occurences.
The conveyor system is full of bugs as well, sometimes pulling items in and out of inventories where items shouldn't even be allowed to flow due to the system not being in a loop, just a one way linear set of sorters, cargo boxes and assemblers.

Even though the maximum speed in the game is limited to a grueling 100m/s, supposedly in order to prevent the physics from breaking, it still constantly breaks, while making travel to other planets a journey that takes HOURS unless you mine for just as long of a time for resources to make and use a jumpdrive.

Starting scenarios are kind of a mess as well, there is no option to just start in a star system with asteroids and limited resources, essentially allowing you to play a survival mode where you can't spawn in new ships. There are some scenarios but they may not include some other generated features of the game. So you either modify server settings on the fly, or tweak your world with the editor in order to have a non-creative, survival experience with all the generated feautres (planets/moons/asteroids) of the game.
If you are completely new to the game you may miss out on these features entirely if you just start one of the scenarios that seem good.

I have the most stable computer i've ever had, reaching 10 weeks of uptimes regularily while playing games and using various heavy applicatios.
I don't think any game has ever crashed my system consistently since i've built my rig 2-3 years ago, yet space engineers manages to do it 2 times in an hour.

So, in closing... People who have played DayZ can understand a situation like this, where the game can be SO FUN yet so RIDDLED with bugs even after years of development, which is what makes this game really hard to recommend, because i DO want to play games with friends.
The DayZ developers worked with a proprietary engine that is very much known to be bug-ridden.
I'm not sure what the excuse of Keen Software House is, as they've been working this engine engine from the ground up, starting with their previous games.
Now they're also working on a game called medieval engineers...?

This game... I hope someday I can change this review to positive but honestly its been
years now and perhaps there have been a few optimizations but it is /still/ a bloody

Let me start by saying I recently re-downloaded this game, after giving up on it because
rather than optimize the game KSH just decided to raise the minimum system requirements
and I did not meet them. Prior to this I was eagerly awaiting the upcoming optimization,
planets, and new multiplayer back end update. All while suffering through the terribly low
fps and sim speed.

I was really enjoying myself on one of the preset earth-like worlds untill it got so slow that
it became a pain to even play(can we say memory leaks boys and girls? :D)

I've now uninstalled it and given up on it a second time.

I have heard KSH and their legion of fans preach "Premature optimization is the root of
all evil." as an excuse for KSH to not optimize their code untill beta. Well let me just
remind them that the /full/ quote is actually:

We should forget about small efficiencies, say about 97% of the time; premature optimization
is the root of all evil

~Donald Knuth

This was born in a time when we still were working with asm. Small efficiencies here literally
meant techniques that would have obfusticated the code base or making various,
per-cpu-model optimizations for a fractional speed boost. This does not mean make stupid
and wasteful choices while coding. This does not mean ignore plainly obvious bottlenecks in
code (I am certain there must be a few with how bloody slow this game runs). This does not
mean raise the minimum system requirements instead of optimizing the game.

It means write code intelligently, which is really not that hard to do if you are capable of
writing even basic programs (think basic utilities or really simple GUI without an IDE backing
you), but don't go nuts on refactoring or writing semi-obfusticated code just to reduce
processing a small amount. It means attach a profiler, determine where the real hogs are,
and address them instead.

I acknowledge that beta is a time of bug fixing and optimization. But that is precisely the
time for optimization of the little things, which is exactly what Knuth was referencing.
Fixing the bugs and optimizing the systems is something that should be done the /entire/

As I said, I have nothing but a few minor issues with the actual game itself (cyberdogs are
one of these issues for being so out of place and immersion breaking), but the VRage
engine is a trashy mess currently and ruins the game for me and several others I know.
I /really/ hope that I can actually run this game some day!

Thanks to whomever reads this, and best of luck to the devs :)

Space Engineers is currently in bata mode, and the team at KSH are working hard, providing weekly updates. I highly recommend this game for players who enjoy building virtual worlds. Since there are so many little peices, an upper end computer is required (X64).

The physics engine that drives this game is amazing, and the developers are smart about encouraging community development, including a strong Steam workshop MOD system. I've yet to play multiplayer, currently content with working im my evil scientist lab.

Have you ever wanted to play a game that had more bugs then a closed alpha? Have you ever wanted to claw out the eyes of everyone around you? Then look no further and welcome to "Space Engineers" where every moment your alive is another moment the chamber just went *click*. You are not mistaken I just compared this game to that of playing Russian roulette but instead of bullets it is bugs. Bugs with; a door, ship walling, placing a simple tire, a body not dropping its items on death, multiplayer net code, solid massive space objects not loading it as you fly into what you thought was open space only to die, and let’s not forget trees that are made of the same metal as the god Thors hammer. Did I mention you can pay money to see these bugs now? It is not even a closed alpha! So join the eyeless empire of those who have lost their soul, money, and humor to this hell gate of a game.

The idea and gameplay* is wonderful and there are wide options for base and ship building. Planets and space are beautifully done and you really get a sense of freedom when you build a ship and launch off the planet. Finding resources and mining is fun (for example with self-made mining ship) and PVP is possible.


Alpha/early access or not, compared to the time it's been developed the multiplayer especially is broken with bugs. Dedicated servers are in trouble with the messy code causing delays all the time and major glitches keep happening all around. Simulation speed suffers immensely for relatively little disturbance (for example someone using too many drills at once). Bugs are currently inch short from breaking the multiplayer game.

Single player is better but still glitchy and demands a lot from your machine compared to what it should.

If you like the genre it still can be worth it to get this game but be prepared for trouble with multiplayer. Game is updated every thursday and we can just hope these major bugs are being addressed effectively. Soon. At this point I personally cannot recommend.

This game was a revolutionary concept back in 2014, and even now it is a pioneering project in the game industry, with full voxel based sandbox system in space with high detail graphics, planets, asterodis, mining, industry building, mechanic systems etc.
Unfortunately it became too big for the developers to finish as a quality game, and the underlying multiplayer concept is not working, it is too late to move to a professional netcode like raknet. This implies, that the concept of faction based, persistent, multiplayer game with lots of players (30+) will never be realised, which makes the game a pointless, unfinished sandbox. It can be considered as an abandonware, stuck in early access, with constant pretense as being fixed, while underlying fundamnetal problems never get fixed.

This game is awesome, although, am I able to play it is the bigger statment/question. Answer: NO!!!!!!!!!!
I have tried to contact the developers to improve the rendering of this game or at the least, offer better graphics options/rendering options. My computer used to be capable of processing this game, but after they came out with the planet update, my computer can't even render a small space station! I have also noticed that there was shading/shadows and pure darkness when enclosed in walls. I have attempted to fiddle with the settings to make it the lowest graphics/video settings avalible, I still experienced problems. Even though I am using a near to death computer now, my computer was capable to operating/running Space Engineers smoothly, but now, it does not!

It's alright, but you'll spend a majority of your time fighting the bugginess of the game. Designing anything requires you to think more about fighting the game's physics and quirks and less about being creative. There are better games out there to vent your creativity. Unfortunately, it's one of the best space builder games we have as of right now.
