I'm not as familiar with other traditions, but - to echo @Bedrockgames upthread - when I watch wuxia films religious characters and ideas seem to figure pretty prominently. Just to give one example, Tai Chi Master is all about Jet Li's character changing from an establishment-oriented Buddhist outlook to a more idiosyncratic Daoist outlook, which enables him to be victorious at the end. Just as I would expect Christianity to figure in some fashion in an Arthurian game, so I would expect Buddhism and Daoism to figure in some fashion in a wuxia game.
Tha is a perfect example. One, Tai Chi Master is an amazing movie with stunning martial arts choreography. But two, it is based on Zhang Sanfeng. It is about the invention of Tai Chi.
