i quoted this, try with a Faction that good Defences, like Carthage, or Macedonia, its hard to go for Victory. i agree with Enrique.each Civilization in game have a Civilization that can do very hard to Win. Example Persian Vrs Atenians, in many Games against Aegis, i never see a Faction destroying a Civic Centre, i Never lost a Civc Center, in Many Alphas.
