The AI in Master of Orion would surrender to one of your rivals just to spite you. That was one of the most realistic features of the original MOO AI. I liked it.
If you want to have 'house rules' in your PBW games go right ahead, but I'm not in favor of any hard coded game restrictions. I wish the SE IV AI would act like the MOO AI sometimes.
