Galactic Civilizations III v1.4 Mega AI update is now available!

Now With Improved AI: Better Planetary Builds and Economic Management

Posted on Thursday, October 29, 2015

New version of GalCiv makes the AI more fiendish, bigger galaxies easier to manage and much more!

For those of you not familiar with Galactic Civilizations III a quick recap.  GalCiv III is a game where you choose an interstellar civilization to lead in the 23rd century. One of these includes Earth in the year 2250.  What sets it apart is the scale and modability of it.  You can literally build up your own galaxy to play in.  When people say it’s the ultimate sand box game, they mean it. 

The game supports over a hundred different civilizations playing simultaneously on a vast scale all while starting out with just a home world. And there are already thousands of custom made civilizations and ships available to download right from within the game.

Solving the AI challenge in v1.4

As others have pointed out, space is big. It’s really…really big. It’s so big it’s as if it has some sort of inferiority complex about itself and it’s just screaming “Hey! You! Look how BIG I am!”  So when writing a game that is part strategy game and part simulation, you have some unique challenges.

For example, how do you write a computer AI that provides a challenge to players without making it cheat like crazy? When GalCiv III shipped, the AI was “pretty good” but it didn’t take long for expert players to find ways to crush it.

So how did we solve it? Data mining.

We started looking at how these experts were playing the game.  Sure, stalking YouTube players may seem wrong but then again, people openly posting their strategies are fair game right? And with GalCiv III being a 64-bit multi-core game, we can toss a lot of computing power at the problem. So we did.

No DLC for 1.4.

For those looking for a new DLC to go along with 1.4, I’m afraid there isn’t any this time.  All our budget went into this free update.  We hope you like it!

Lots of other stuff

The AI wasn’t the only thing we worked on of course.  The multiplayer community of GalCiv III continues to grow and we’ve put in a lot of work to make that a much better experience since the game does lend itself to multi-day sessions of MP (though I wish  more people would play the Arena maps but I digress).




Nothing exciting, I just love the idea of starting in our home solar system.


Governor Planet 2

Much better chicks to get information on your world.



Emphasize the production of a planet or turn it over to the AI to manage (with an all-new, written from scratch planetary governor AI)



The Ship designer remains one of the coolest features of GalCiv III.  Remember: The AI will use your ship designs when you play against them. Also, these cool ship designs are available via Steam Workshop so you can import them into your game (or print them to your 3D printer).


Player designed ships leads to some interesting battles..(yes, that’s a space hair dryer)


Players can share their designs online for epic…Lonestar fun…



You can also zoom out to see your custom made galaxy fighting it out


Import alien races created by the community into your game for massive galaxy wide diplomacy, trade and warfare



The Full Change Log

The AI Strikes Back! The AI now does a much better job of building its planets and managing its economy. Player Governors are likewise better at building planets and the new Spending Foci allow you to manage planetary production.

+ The AI does a much better job at building worlds
+ Added AI governors to better manage starbase construction
+ Improved budget management
+ Improved constructor movement logic

+ Player governors do a much better job of building planets
+ Added spending foci to the planetary screen. This allows players to shift their planetary production between manufacturing, research, or wealth.
+ Added a Balanced Governor type that builds worlds that are balanced between manufacturing, research, and wealth spending.

Change Log
AI Changes
+ AI creates specialized planets instead of generic worlds.
+ AI prioritizes building starbases around planets instead of strictly claiming resources.
+ If the AI determines that it is overspending and cannot support the fleet size, it will aggressively decommission ships. Older ships are decommissioned first.
+ Improved AI and Governor planetary project (e.g. Economic Stimulus, Cultural Festival, etc.) selection
+ After conquering a planet, AI will pick Governors based on the existing improvements.
+ AI now picks Governors based on planet bonuses.
+ AI now uses spending foci.
+ AI tech Governor now has a better tech order provided.
+ AI will no longer overbuild starbases and it only builds what it wants to build.
+ Add Governors for the AI to manage Starbases.
+Tweaked the AI War strategy to focus a bit more on Research.
+ Improved Constructor movement logic:
- Constructors will no longer get stuck in a logic loop when entering dangerous areas.
- Fixed weird edge cases regarding constructor building rings and resource capturing.

+ 10/27 Made the AI research weapons better by increasing the priority of all weapons types slightly to work better with tech governors.
+ 10/27 Added multiple new AI prototype blueprints and designs such that the AI is now much better at using Resources to kill you.

Known issues

  • There are some cosmetic text issues on the Hebrew version of Windows in some of the tooltips.
  • If you haven’t run the game since upgrading to Windows 10 and the last time you played was earlier than 1.3 the screens directory might not work right resulting in launch issues.  If this happens, delete the GalCiv3 directory in documents\my games.
