Thinking back to Civilization II, you could focus your attack on the other civ's capital, and if you took it, there was a chance you would start a civil war in the country. I'm not sure if there's a chance of doing this in cIV, but I haven't seen it. In any case, this was one of the things I looked forward to in Civ II (of course Civ II was my personal favorite). Is there anyway to mod IV to do the civil war split? Or will we just have to wait for an expansion/Civ 5?
