Man that's lame. :/

Meh, you could just take the lazy approach and just put in the warring Chinese states and the Mauryans (maybe the Xiong-nu as well) and just make all the rest rebels with a nice little descriptor building. :D

Hmm, Earth: Total War! Spanning several centuries and the entire globe! :D Now that would be EPIC (and taxing on one's comp! :p) You know like EEIII without sucking. Oh well I can still dream! :(
