I definately like the civil war idea as well. The way it was handled in Civ I and II was very balanced, and did not upset the gameplay at all. In fact, in early games, it made the mad dash to take the capital city while the empire was suffering from low morale a major strategic endeavor. I'd give it a 10 as well. As others have stated already, I do agree with the toggle at game startup to switch this feature off, if need be.
