No, Jade Empire sucked. I felt ripped off when I bought if for PC then, I still don't think it's worth the price now.
The setting is interesting, I'll give it that, but the story, characters, gameplay, length, and hubs were utter trash. For the price I paid on the PC version, it was a ridiculously short game that did not live up to the coverage it got at all. Your character visits like 3 main hubs (small hubs at that) that not only felt lifeless, but lacks all the grandeur I was expecting from visiting and Imperial CITY.
The game itself felt ridiculously rushed. When I first saw the world map I was like cool that is a pretty big world map, but after unlocking three little sections on the bottom cluster of the map, the game is done really hurts. Again the setting is pretty, but really nothing out of the ordinary.
My biggest problems with the game is the retarded morality system Bioware likes to do and the spirit world. So much could have been done with the spirit world but you only visit it like 2 times, both of which were underwhelming. The twist was not surprising at all to me and from the first time with the fox lady, you would expect to visit it more, but you don't.
As for the morality system, it is literally light and dark from star wars disguised as 'closed fist' or 'open palm'. Closed fists advocates fighting for yourself, helping others becomes stronger ect. while open palm is more budha in teaching others enlightenment, peace, harmony, ect. but the choices given are very clearly light and dark, evil and good. The only good morality system from Bioware that I like is Dragon Age Origins (as in there is technically none).
The combat was meh, the styles were stupid to me, as were the weapons. The controls itself were clunky and magic was useless plain and simple.
I would also like to point out that the demo from for the xbox when OXM was around was ridiculously different and misleading. The demo features a battle in the spirit world with and adversary that gets killed in the beginning of the actual game as well as a battle at the monk temple which was also much more grand than the actual one.
