I "played" it for a couple of weeks back in early '09. I mostly went around trying on outfits for my avatar, and occasionally talk to random people if they decided to talk to me for whatever reason. There was a pretty neat FF VII build where fans would gather and roleplay. I didn't do that, but I did take a tour of the place. Pretty cool to see all the work and attention to detail that went into it.

Other than that, I got bored pretty quickly and haven't tried it since.
