BTW the univercity send a planet buster near my capital destroying a city 5 square from capital and making a nice acces to sea (from this city i was loading transport full of army to fight ) I build gaia52 on this sea

The other factions will absolutely refuse to deal with you and never even sign Treaties with you if your reputation is bad enough. It also lowers the "AIs begin to unite against you" point, too.
