E3: Civilization IV

[A Black Falcon]

Civil War? Like what? You want there to be a chance that your nation breaks apart? There is a thing where cities near other civilizations can be consumed by them if their culture is a lot higher than yours, from Civ III, but yeah, nothing like rebellions, revolutions, civil wars... but how would they implement it? Really, it seems like it'd be pretty tough to do with a game like Civ.

Even so, it looks like they are making advances --

Ideological conflicts are a definite possibility as a result of the AI leader personalities and their ties to certain religions or civics.
