This sounds like a great, if work intensive, idea. China and other Asian countries are going to be hell to represent properly though. It will involve making new units, models, buildings, technologies and possinly even new vegetation if you want to do it properly.

If this goes a head I would be extremely interested however. Asia is sorely under represented in TW games and is in serious need of a modern update since Shogun. It would be nice to see Japan and other Asian countries as factions .
