the problem is: the AI is coded to be a sucker for map information/aliances/trade rights... if one sends out diplomats in all possible directions at the beginning of the game, it is possible to stall AI's development sucking out your neighboring factions' cash for the map deals. this is great to jump start your own economy. the downside is though: the AI is underdeveloped and the game gets "easy" aka "boring"... :)
