I dislike Jade Empire in many ways... mostly because I am actually Chinese, and I am familiar with Chinese cultures, traditions, contexts and characterizations, and Jade Empire got too many things wrong. The whole experience just felt, off.
At the time I liked to compare Avatar: The Last Airbender to Jade Empire. Both were fantasies and mythologies that were based on China, created by white men. Avatar: The Last Airbender was created by white men who actually knew and understood China and being Chinese, (as amazing as it sounds,) while Jade Empire was created by white men who were... well, clueless about China and Chinese in general, and did not bother to do research.
No offense, just how I felt about the game. It was still a fun game though. I just wish it was not set in some mythological Asia. Playing Jade Empire was like, hm, watching a bad Steven Seagal movie, (I do not remember the title.) He was supposedly trained and spent years in China, and then he pulled out some ancient scroll that was supposed to reveal some ancient Chinese secrets... and the writings on the scroll was in Japanese. I'm Chinese, of course I went "WTF?!?" and had a good laugh. But if you are white and have rudimentary understanding of Asia and Asians, I suppose it's perfect.
