About This Game

Take command of a vast interstellar empire and safeguard your species from total extinction in a procedurally generated 3D galaxy (with the option to flatten it) from 1 System to 10,000+! Prove your species' ingenuity through a deep and intricate combat system where anything (from individual components on ships to the stars themselves) is a target of opportunity.

Twist other Empires into submitting to your galaxy-class wit with diplomacy and wheel-and-deal your way to supremacy.

Research new kinds of weapons, engines, shields, and more, all of which retain their unique benefits as the game progresses, with a research web whose contents are shuffled every game at your option.

Exploit interstellar phenomena such as asteroid belts and stars and exploit them for yourself or destroy them to deny your foes. Create and destroy new worlds through advanced technological research.

Match your strategy against up to 10 other opponents (online or LAN-linked). Save the game when dawn breaks and boot it back up at dusk. It isn't over until you say it is! Drop in and drop out at any point; disconnecting players will not disrupt the game!

Your weapons, your ships, your rules: Almost the entire game can be modified through Notepad! Easily add new models and particle effects to the game with “out-of-the-box” developer tools. Create new weapons in seconds; create new AIs through scripts! The Galaxy is yours!

Just finished the tutorial and... Wow! this game!.. It has got the best of every 4x game I've played till now.

So what should you expect?...
...Expect a Space Empires game (a turn based 4x) minus warp holes for inter-system travel, with RTS elements of Homeworld on a game engine like a AI War: Fleet Command. Oh! Forgot to mention, Star Wolves like pirate raids. :))

It is a close to perfect 4x RTS game which doesn't need a hefty system specifications to run on with guaranteed tonnes of hours of gameplay. The reason I called it "Close to perfect 4x RTS game" is because I havn't played long enough to be able to comment on AI. But I'm optimist it won't disappoint.

For now, 10/10 for game design and controls... Will update this review after playing a couple of hours with AI.

Update: AI
Now since I've played close to 19 hours, I guess I pretty much understand how the AI's behave.
Initially I thought AI to be easy, but couple of minutes later, game proved me wrong.

Unlike other games, where AI's target you when you are supirior to them or become a threat, in this game, they will ensure that your race is wipped off the galaxy if your race is inferior to them. If you however are superior, they are likely to give you resources and research points to stay your ally. I'm not saying they won't attack you if you are superior (i.e. leading in number of ships, research, star systems inhabited and economy), but that in my experience will only happen if there are no more planets to colonize.

AI's can also become annoying at times with constant treaty requests. While most of the AI's rely on medium ship sizes (usually 10x-50x), some will build gigantic ships (like 100x or larger) couple of minutes in the game. So I suggest you to try to build some for yourself.

Also, build a huge number of ship so that you have enough reserves for ones you might lose in battle. As if your fleet size is minimized, most of the AI's will turn their backs on you and believe me, thats disasterous!!

+ the massive scale is amazing. You can make galaxies as big as you computer can run.

+ the scale is not just limited to the galaxy the palyer can make some massive structures like a gun that can destroy star from other star systems and ships that can be larger than entire planets

- the diplomacy has nothing to it all the options are just to make a threat, demand, allaince, or war. The playere literly just selects on of those optins form a drop down by the race which give no satification

- the economy is just one resource really and that is ore the other two resources are just refinde ore and refined refined ore so it pretty one dimensional

- the research system can be quite intersting where the player can infinitely research a tech at exponentially higher cost to continue to gain advancements in that field the bad part to this is that advancement feels very incremental for the most part which it is. This takes away a lot of the excitment from researching a new technology because the not a ton can generally be done with new research advancments.


I have defeinately put quite a few hours into this game and definitely had some fun with this game but at the same time I do not feel like I can recommend this game to others. This is mainly due to after playing for a while I do not feel this game really has much of a soul to it and in my opinion can be a bit lifeless at times. I also had this same feeling playing x3 where the whoel universe just felt overly mechanical.

This would be an alright real-time space 4X if if weren't for one feature - you have complete control over the size of your ships. Yes, it is theoretically possible to build a ship larger than the galaxy. Do yourself a favor and construct a mega-flagship whose quadrillions of crewmen have never seen the outside world.

When a game makes it a struggle enough just to chug to the end of the tutorial, you know there's a problem. I'd sooner have fun completing every tutorial in every paradox game ever made than try to do this tutorial again. It was just too boring. It taught you what felt like everything the game had to offer, and yet I still got into my first match feeling like I've learned nothing at the same time. And here's what I learned in my short time in my first match and in the tutorial of this game.

+The game takes a unique spin on the RTS genre, points for bravery.
+You can raise literally a fleet as large as your CPU can support. That is astounding, and really helps the combat element in this game.
+/- A very unique take on planet management, one that is complicated to understand, but also sort of interesting to toy with. Every planet forms a web of resources, and can be tailored by your or an AI to a certain task.
+/- Resource collection feels lacking. everything essentially starts as ore, which then gets processed into countless more complicated resources to tailor to specific production. Ore is limited on a planet, so you need to keep expanding or also begin to take advantage of asteroid fields. I've never been a fan of "One resource" strategies like that, especially when you then need to tailor certain planets into factories to turn that resource into a specific production part. It just seems like a needlessly complicated version of what should be something simple, and I just don't like it.
-The tech tree is bad. Instead of researching specific techs, you have this strange map of generalized tech types. You can queue different ones for research, or just leave it on one type, and watch as they "level up". This doesn't provide you with anything new really, it just upgrades the effeciency of what you already have. To update your ship with "new" upgraded tech you hit the "update" button on the schematics, and then retrofit. You then watch as no visible change is made to the ship, but know deep down that somehow, it is better that it was. Even if it's completely unobservable.
-Diplomacy is pointless and makes no sense. I can't have a peace treaty without an expiry date or it lasts the entire round? What the ♥♥♥♥? Ever hear of breaking a treaty? How declaring war nullifies treaties? I don't want a match-long peace or alliance I just want one that ends when I or my ally chooses to end it, not at the end of 1-10,000 seconds. Oh, and no normal human being counts time periods that long in seconds so what the ♥♥♥♥?
-Ship design is utterly confusing/under-done/needing a complete redesign. Essentially you just drag and drop modules, hulls, engines, and etc onto a flat square that is supposed to be representing your ship. They tell you placement matters, if you put it towards the front, it will be in the front. If you overlap it with another module, you may get some bonuses. Why the hell is it apparently so complicated like that then, if I'm designing a ♥♥♥♥ing square? I don't know where things are going to pop out on an aerodynamic long-shaped ship when I'm designing a god damn square! I don't know what these "bonuses" i get for overlapping things are, because nothing in the game teaches you this. This is a pathetic way to go about ship design.

I could go on ranting, but I'll end by saying that Star Ruler is a game you play only when you have NOTHING else to play, at best. I give this a 3/10. It has potential hidden in there, but I can't bring myself to waste my time trying to see if it ever shows itself. I certainly hope Star Ruler 2 is better than this. Because you should avoid this game like the plague unless it's on a very cheap sale, and you have literally nothing else to play.

If you like Total Annihilation / Supreme Commander types of rolling economies - then this is the 4x for you.

Tired of the constant back and forth over a single star system on the edge of your territory? Simply destroy all the planets and the star they orbit and your problem is solved!

Don't like how looooong it takes to build those 1,000,000 kilometer long ships? Simply build a Ringworld around a super giant star! You can build fleets in the 1,000's in just seconds!

But wait! "Building that Ringworld is going to take too long!" Sure, while that might normally be true, all you need to do is build planetary thrusters on each of your planets and fly them all into a single system. Take that logistics!
