So far I have only tried EAW on medium difficulty GC, going to try hard today. But on medium, the enemy AI never techs up as described above. And what is worse, they never build or upgrade their starbases above level 1. I did an experiment. When I was in pretty much control of everything except 10 enemy planets, I went around with a fleet and destroyed everything in space above their planets, ships and stations. Then I transferred my fleet back to my territoriy and set the game for accelerated time. I went to the store, I made some dinner and even watched a movie on television. After almost 2.5 hours I returned to the game, and all I found was lvl1 spacestations above all their planets. No fleets. This was a bit....sad. Anyone know how to make the AI work?
