Age of Wushu is an intriguing free to play MMO from China. You play as a martial arts expert, but there aren't any levels or character classes. You learn your skills from one of eight schools of combat, and will be able to raid other schools to gain bonus knowledge and unlock more abilities. You'll be able to train your character outside of the game as well, using 30 "offline activities."
