You can see factions invoved in the game in the thread 'About the Mod'
The revoulution will happen like the Marius Reforms in R:TW, a message will come up, and then Cities may revolt, they revoulution only happens in certian Ctities I think, still deciding.
The Americans may come in as the Mongols come in. They just appear.
Right now I am deciding whether to keep it based on just America, it is being thought that a little bit of Europe and Africa will be included.
South Africa will be like America was in the M2TW, on the side of the map, though it may change. The Colonies in the Far East? Do you mean the Middle-East? If so there was no colonies there. If you mean Asia then it probaly wont be included. If it is and Europe and Africa are, then the mapis just to big, but ig you say... Does that answer your questions?
