If you’re not familiar with Galactic Civilizations then you are in for a treat this May when Galactic Civilizations III ships.  GalCiv is the ultimate sandbox game. The universe is your domain and you are in charge of a fledgling interstellar civilization.

In order for the galaxy to be immersive, the computer opponents need to be interesting, challenging and intelligent and do so without having to rely on cheating.  You can play multiplayer but we don’t want to have to rely on that.

The starting conditions

In this corner, those crazy primates of Earth we have the Terran Alliance!

And in this corner, we have those blood thirsty beasts of Drengi of the Drengine Empire!

And in the middle…

This amazing star system.  Each player has a very different AI personality.  But which one is more effective? Today we will find out as it’s AI on AI combat!

Game I

Turn 0:

image

Let’s see what they do…

 

Turn 40:

image

The Terrans rushed to get planets while the Drengin focused on getting war techs Who will benefit?

Critique: Both players focus too much on fortifying starbases rather than grabbing more resources.

Result

image

Human victory in 120 turns.

Let’s try again.

Game II:

Same game conditions. Terran victory after 150 turns.

So what happened? Drengin didn’t protect their planets, didn’t build economy. Too warlike.

Game III: After working on the Drengin AI and general AI

 

Now with lots of players:

Interesting. I've always wondered how developers test ai in a game like this. It seems like it would be a time consuming process.

I dont find that surprising...considering that the Drengin are concerned more about war and conquering then focusing on economy and wealth...it seems to be a correct way for such a war like species.  While the Terrans are concerned with wealth and research and only fight when they have to...to me this seems right and when the 2 collide...well i think the results speak for themselves.  Granted I dont know all the specs, but are you really wanting to make the Drengin make other things more important than war?  To me, they are like the Klingons...and as such they cannot respond to events that happen as quickly as other races...say like the Terrans or Federation.  Thus, while the Drengin may have enjoyed some early victories(or not, we dont know) in the end they are beaten by a faction that can throw more ships at them and replace loss faster than someone who does not have the economy or research base to respond in kind.  That being said, if the Drengin had been even more aggressive and attacked earlier, limiting the Terrans on what they could gain in both economy and tech...then it may have gone much differently.  Just my few thoughts on why we beat those damn dirty cats!!!

Seems like the Drengin got overrun by bad influence generation.  They probably also forgot to get multiple fleets out, and forgot planetary invasion techs.

 

One thing I see the AI doing is sending a single ship (usually powerful) off to wander around, rather than purposely making fleets maxing the logistical components (or even researching the logistics techs).

 

Also, totally forgetting planetary invasions.  Wars before planetary invasion are just starbase and ship yard smashing.  They can't do anything about the influence generation, so effectively will still get ran over.

Cats?  While I have to admit that they are somewhat similar to the "Kilrathi" (from the "Wing Commander" franchise); I've always found them to look more like oversized and Apish Chimpanzees.

Just saying.

ive seen them referred to as "cats" many times on these boards...from GC 1 on up...

 

Just saying.
