I really enjoyed playing your scenario, over the weekend. All three positions are winnable.

Knowing nothing about Chinese history I cannot (will not) comment on it's accurracy :))

From a game play point of view you might want to consider alter the VP conditions so that the smaller postions gain from simply existing. Additionally you want want to consider either "Barbarian" Hordes or external nations as a game balance tool. I'have no idea if that happened or not.

To close I liked it alot and am looking forward to the next in the series

was this a reply that you accidentaly clicked new thread for?

Yeah it would be. Probably one about China and "Barbarian" Hordes. Most likely that Three Kingdoms one.
