What MMO would you like to see made into a movie?

So, that WoW movie has an official release date. It also has a skillful director, which is both good and bad. It's good because Duncan Jones may actually make a watchable film from video game source material. It's bad because I would've gotten a laugh out of Uwe Boll or one of his contemporaries soiling Blizzard's brand on the big screen.

At any rate, assuming the WoW flick is financially successful, it could possibly pave the way for further MMO-to-film adaptations. Is there a particular massively multiplayer property you'd like to see made into a movie?
