Thanks Garret, and the map is pretty useful, but what I meant was, how did you decide which cities were going to rebel and so on?
Edit: also, are you going to have an 'international' type scheme (like the Spain 1936 mod) whereby groups can receive reinforcements from other countries? And are you going to allow situations where a city will revolt and join the other side, for example if they have the wrong ideology and unhappy and so on? It might make 'missionaries' more important. Perhaps ordinary troops for the rebels could have a chance of spreading their ideology to cities they capture?
Edit2: Yeah, I found that when I was playing around with things. My only suggestion is to fiddle with the cities and get the cultural boundaries to be set roughly right.
Edit3: I suggested this for another mod, I think, but it could also work here, if you can do it. I think that territory should be gained and lost according to where units move. So if I move tanks towards an enemy city, every tile they cross will become my culture, for a limited time.
