i mentioned it before but thought I'd mention it again. Second Life has a Buffy the Vampire Slayer sim that is incredibly realistic and tons of fun. It's a role playing Sim where you act out scenarios with your buffy character (kind of like a real life fanfic) 
Here is a blog that you can see what kind of things are role played
