In case someones interested, here are some results from early game tests. It's really difficult to force the AI to do the same each time you replay the game.
The dates for people are the time they met the player (the player founded its first city and did nothing at all). 'Avaiable' means the player had access to a religion at all early on. the 'c65' numbers is the AIs city count.
