If you take history as written knowledge, doesn't the West have more texts describing martial arts maneuvers than the East?
Since we're talking about a game, you could make it so that in the west, teachers would have schools where they teach nobles and rich people, or train professional soldiers, while in the east some teachers would be monks in a monastery, others would be craftsmen of their village, etc.
EDIT: also, in case I haven't posted it yet...
some interpretations of Hans Czynners treatise on harness fencing from 1538
EDIT 2:
Wrestling blindfolded
This would be an awesome scene in a game (even without the blindfold). You finally get accepted as a student to a really expensive school, and all around you people are practising with swords, wrestling, trying out different stuff. Awesome!
Edit 3:
