I was wondering if anyone had any suggestions as to why this happened...

Last night I played a sandbox game: huge, seven other races at tough. All races had the same intelligence, gifted I think and I had Tech Victory off as well as Tech trading off and blind exploration on. Habitable planets were abundant, oh and Tech research was set to slow. I grabbed a handful of planets early on and and continued to get a few more every two turns. Long story short, By the end of the game I had about sixty planets as well as 3/4 of the galactic population. The AI for all seven races had two planets each with their best tech as research academies (I had done nearly every tech there was). I had even made 14 high speed colony ships and given two to each race in the hopes that they would claim some of the 100 class 10+ planets left over. It didn't use them. I think that it may have sold them for cash because they all seemed to have two planets later on.

Why did the (overall) AI do nothing all game? It didn't even declare war on any one. In the end I just made alliances with six of the other races as the Korx wouldn't. I blew their two planets out of the galactic water. I wanted to play a game where the AI had the same advantages as myself but it did nothing.

Any suggestions... Game still rocks though
