Hello,
my name is Alexander Souslov, I'm a producer of Snowbird Game Studios, the developer of WFAS. As far as you distribute you mod for free, you have no problem using our content. So please do not be confused with these comments at the forum - definitely you can use models from Warband or WFAS or any other game.
By the way, we now lucking for a chance to release our next game - Caribbean! - in China. May you please tell us, is there any market in China for box version for PC-games? Or a piracy is an absolute power?
Regards,
Alexander
