v1.8 Update with Asteroid Mining and More Now Available



Mine Asteroids, Level Ships, and Experience Improved Multiplayer in v1.8 of Galactic Civilizations III
New features, updates, and adjustments to the base game. For a full list, see the change log below!

Asteroid Mining
Looking for a get rich quick scheme? Well, this may not quite fit the bill, but it will fill your pockets! Choose an asteroid in your zone of control and build an Asteroid Mining Base. When completed, it will send raw production to a planet of your choice. make sure to keep an eye out for your enemies, though -- these bases are fragile and easily destroyed.

New Planet List
There are a lot of planets out there just waiting to be discovered! This new planet list allows you to keep track of the planets you've already found so that when you go back to colonize them later, they're much easier to find.

Ship Leveling
Win battles and survey anomalies to level up your vessels! Most ships will gain additional hit points as they gain experience and Mercenary Ships will improve based on their existing abilities, which makes them a lot more relevant in the late game.

Star Information Window
Click on a star to see all colonizable worlds within that system. Organize your empire by renaming stars with your own name scheme - or, draw inspiration from your favorite Sci-Fi series!

Multiplayer Improvements
Enjoy new stability in your games online with friends! The game has been updated to allow for increased ship movement during multiplayer matches and a host of fixes for issues that could cause desyncs.

If you've been playing Galactic Civilizations III, we want to hear from you! Join the conversation over at Steam.

About This Game

Never the same game twice, Galactic Civilizations III is the largest strategy sandbox ever made. Each new game offers an array of options as you set it up - choose your map size, abundance of planets and resources, frequency of events, and more for a unique play experience every time. Galactic Civilizations III also removes linear victory conditions and offers you multiple objectives that you can choose to pursue in order to win, such as military conquest, cultural domination, technological ascension, or political alliances. The new multiplayer capabilities also allow you to expand your challenges and fights beyond an AI in order to face off against fellow players. All of this, topped with a rich and in-depth custom ship designer ensure an immersive and exciting experience as you decide how to rule your galaxy.

CORE FEATURES:

  • Never the same game twice: Play in the ultimate sandbox where each game has a unique map, worlds, and challenges to face -- all on a massive scale. Play against 16 to 100 opponents.
  • Multiple paths to victory: Win through military conquest, cultural domination, technological ascension, or political alliance.
  • Story-based campaign: Get brought up to date on the 20-year story arc behind the rise of humanity in the 23rd century.
  • Massive technology tree: Research a technology tree with immense breadth and depth. Each playable faction has their own unique specializations. Your choice determines how you play and win.
  • Faction & Ship Customization: Create a civilization with its own look, ships, technologies, and even options for how the AI will use them.

  • New Battle System: Assign your ships specific roles to play in combat. You can now view fleet battles in a cinematic style to see your designs in action.
  • New Colony Manager: The location of a planetary improvement now matters. Adjacency bonuses and planetary resources make a major impact on what a planet is strong (or weak) at accomplishing.
  • Planetary Governors: Utilize individual planetary leaders to govern your worlds, deciding what improvements to build and when, which leaves you to focus on larger strategic goals.

Bought this game when in beta, always crash in game after awhile. Expecting fixes at full release but, instead, see DLC after DLC coming out asking for $5, $10, $15. Very disappointed with the way they make games nowadays.

Game play is alright until early mid-game when things get repetitive. They put new features into DLC before even getting the basic features right.

Do not buy this game.

I've sunk a fair amount of time into this game, started multiple files and I've gotten decently far in each file only to have the game hang on me every ****ing time. As early as turn 81 and as late as turn 146 (because that's literally how far i'll get into a game before it happens) one of the AI players will crap the bed and my turn will never come. It'll say "Starting new turn" down there at the bottom corner where the next turn button is and I won't be able to move any of my ships, queue up any new projects, research or constructions or even save or load the game. I can't even get back to the main menu.

Ive had this issue since I first got the game. The support ticket I sent in almost a year ago was never replied to, none of the patches or DLC has fixed this issue and it has happened in every single file I've started. I can't recommend this game until this problem is addressed correctly.

I like it, but it has alot of issues in its current state, I would like to see more free content/features out

Pros:
Reasonable AI
Alot of customization is possible
Decent community content
Massive maps are truly massive

Cons:
Gets sluggish even with 16GB RAM as the game goes on
DLC DLC DLC DLC...base game is just that, basic, pay to unlock features
Unstable, make sure you enable auto-save to be frequent, I've lost alot of progress in games
Unless you got a powerhouse machine, it seems biggest maps will bring your PC to a stop

Bought this game to play with friends, and multiplayer didn't work for a single one of us. Instant crash to desktop every time.

We all got our money back, so at least the one thing that worked was Steam Support.

10/10 crash experience, highly immersive

**UPDATE**

We have discovered the issue, it seems to be able to play with your friends they MUST have the same DLC as you. So if you intend to game with friends, be sure they have all the DLC that you do, otherwise you are wasting your money.

I really love this game but is it at all possible for you guys to fix the crashing? i mean sometimes i wait 5 minutes before realizing the game will never catch up i understand the game is massive and even more so depending on the size of the map but when a small sized game can last 24+ hours i expect to be able to sit and play for at least 2 hours before the game completely ♥♥♥♥♥ itself and crashes. Also it would be really nice if you guys were a lot more honest about the ram demand because if you have yet to purchase this game and you run with even 16 gb of ram the game cant wait to crash. This game is definately worth the purchase what little i can actually play before it crashes. The crashes have become even worse now with even more ♥♥♥♥ to populate the screen. Can we focus on one thing at a time i do not think we really needed mining facilities on the dead rocks but who the hell cares lets continue to add more and more ♥♥♥♥ so the game will never work unless your sporting 64gb of ram. I cannot at this time recommend purchasing this game for in its current state it is infact unplayable.

Well... I bougt the game because of that i loved Gal Civ 2.

Gal.Civ 3 is perfect if you love chrashes and repeating pointless stuff. And of course, insted of fixing the game they make DLC, lots of DLC.

Because of the abusing of DLC Stardoc is now on the black list togeather with Paradox.

As a big fan of Gal Civ I and II, I was excited for the third. This game is not like those. The originals were epic and complete strategy games with a charming miniamilst indie-style. Part 3 is actually a DLC purchase simulation game, where gameplay consists of buying and downloading tons of nickle-and-dime DLC, which trickles out every so often. The original game is so short and shallow, I thought I had completed the tutorial only to discover the campaign was over. This game was just a shell onto which endless DLC is piled. Features that were in the original games were removed from the third, and repackaged as DLC (with some features still missing). Stardock once held the title as "most trusted developer" in my book, but things have changed at the studio, and their products are absolutely awful rip-offs now, and Stardock should be considered a scam company. (See also, "Elemental" for another example of a rip-off game from these developers).

I'll preface this by saying I have purchased all of the GC games and like them all. The one thing that has become more obvious is the tendency towards releasing a very early, base game and using DLC to spice it up and make it seem more interesting. A "Season Pass" is the standard it seems now....

This game, even after a year of being out and having been patched all the way up to v1.8, still has major bugs and memory leak issues. Any of the larger maps are not able to be played to completion due to memory issues and performance lag. The machine I have has 16gb of memory and still has issues. One bug (destroy a planet) has been in the support forums since early 2015 and still hasn't been addressed. The keyboard shortcuts and game documentation leave much to be desired. Not enough shortcuts and too much repetitive "point/click" items.

This is an amazing 4x space turn-based strategy with some depth and an AI that isn't asleep at the wheel. Unfortunatley I've finished 1/4th of the games I've started in single player and none of the multiplayer games.

I got this game for myself an my wife, we love the Civilization series and I had played previous Gal Civs before, we picked it up and got hooked. But then the game crashed, eh that happens no worries. But it keeps crashing, we've jumped through the various tech support hoops and its still unstable as the day we bought it.

Specific and unavoidable parts of the game seem to force the game to crash on a regular basis, like someone defying the U.P. Vote in multiplayer seems to always kill the game for myself and my wifes copy independently of each other. This, along witht he trouble shooting we tried, tells me the game is faulty.

tl;dr crash happy fun 4x game.

This game is really addictive and fun, but buggy and unstable. I keep starting games and right as they get fun I have to abandon them because they keep crashing to desktop. Specific random events trigger this, one I pinpointed to a shipyard being destroyed, and I just encountered it again after wiping out the last Klingon planet. Often if a downloadable ship belonging to a different faction than the one you're playing is chosen, the game crashes too. And that's not counting the litany of weird little quarks, like having the starbases randomly revert to the oldest, worst kind of constructor ships when they "order" their upgrades.

I would love to recommend this game. It's a nice, quiet 4x afternoon with a lot of beautiful custom ships from the modding community, but it's just too buggy right now. Hopefully the product managers let the devs focus on stabilizing the game instead of trying to pump out more DLC for 5 bucks a pop.

Stabilize the game guys, then I'll buy the DLC, I promise. Until then, meh.

Unimpressive. It's the same old as the other games in the series, a few minor tweaks (race design) but nothing to write home to mum about. For me the biggest two problems with it are in order to have even a most basic overview of what is going on you have to zoom out - when you zoom out the display becomes a 2D hexagonal grid full of stylised symbols for ships, planets etc making the whole thing look like a 1980's table top strategy board game. The graphics are nice enough up close - when you are so close you literally can't do anything worthwhile.

The second problem is the ship designer - probably the games greatest asset. It is fiddly to use at best, the rotation dials are nightmarish and as far as I can tell you can't rotate the 3D model to get a good look at what it looks like from the front/top/side as it is permanently shown at a 45 degree perspective. I tried 4 basic ships and saved as templates, each saved but without any active modules (ie the entire hull configuration was there but missing the colony pod, same problem with constructor module etc).

Don't get me wrong, the game is ok - so was GCII with all its variants and this just seems to bring not much new to get excited about.

=) Hours later....sudden afterthought, this thing is moddable which I haven't explored so the community may save it contentwise.

Played many hours of GCII, but this one leaves a LOT to be desired. I know there are fanboys on here that swear this game is great and it's easy, and it's the greatest game ever made, but they are obviously cheating, or modifying the game files.
For the rest of us, it comes down to the AI having a HUGE advantage over the human player, even on easy. Resources, FoW, manufacturing, etc. You HAVE to research weapons, armor, sensors, and other military techs from the start, and you must produce ships every turn as soon as you can.
On easy turn 800 or so, the power indicator shows AI having 32000 and I have 2800. This is after researching all of the available weapons and armor tech and putting out over 100 ships. There is NO way a human player can do this - without cheating. It's imp[ossible to put out 32000 points of ships. Survey and sensors are the same way - the AI can and will move faster than you, and make a bee-line for you even though it shouldn't be able to catch you, or to see you. Don't waste the time on this game, unless you want to use cheat codes or modify the game files.
