I've recently been playing
Silk Road Online. It's a great MMORPG and it's free (you can buy some bonus stuff if you want to though). Its theme is based loosely around the time of the Silk Routes to China. I've only been able to play a Chinese character so far (lvl 14 now), but the graphics are pretty decent and gameplay is rather nice. Only problem is the fact that the server are often very busy... especially in the evenings in the EU timezone (when I was in Ohio, I could always log in around 8 p.m or so, btw).
