I just bought Conquest of the Crystal Palace for my Nintendo Entertainment System, (great game!) and I'm kind of digging the classic Chinese motif right now.
I can't think of too many other games with the ancient China theme...
Kung Fu
Conquest of the Crystal Palace
Little Ninja Boy/Brothers, Kung Fu Heroes (Culture Brain's "Super Chinese" series)
Jackie Chan's Action Kung Fu
Chew Man Fu (TG16)
Romance of the Three Kingdoms (I don't like strat-sims!)
Warriors of Fate (Capcom arcade game)
Knights of Valour series
Martial Masters
Can you think of any?
