9dragons used to be okay, but then they added the permanent immovable ad banner on the top of the screen, which destroyed what little immersion there was. I can't feel excited about kicking the crap out of zombies when I'm being flashed Viva Pinata ads constantly. Also, for a martial arts-based game, it's rather curious that there are no physics whatsoever. Hell, you can't even jump. Everything's done using scripted animation. Eh.
Needless to say, most free MMOs (and holy crap there are a lot of them) aren't worth playing.
