What do people think of the AI? Even at high difficulty levels I find it to be about as clever as my dog. I read reviews saying the AI was very good but its terrible. They hardly ever attack my transports even when right next to them, they have whole fleets that are useless because they give them crap engines and most of the planets I take off them haven't even got factories. Is my copy of the game especially stupid or is everyone finding the game way too easy?
