Hi, this is the very updated version of Chinese Fortress V2, I guess there were some bugs in it. This is the refined version and imperials in 30 mins (It does imperial this time).
It can withstand a powerful force in the Imperial-age and late castle but will collapse when resources are out (wood).
I hope you enjoy it, I also included a variant of this Ai which playes Byzantines, it's strategy is somewhat different and may bring you surprises (it did better than Chiense fortress at the Ai tournament at aiscripters.com)
