Hey Tan, I really like this idea. Actually I have been waiting for an East/South-East Asia theater to be out in a TW game. So until they make an official one, this mod will be a great satisfier for the TW asian fans out there=].
If you can, it would really be appreciated for more up to date updates on this. I'm really excited.
Really thank you for attempting this
P.S
This might be totally late and too far into making this mod, but won't this fit better in Shogun 2?
