Bejeweled add-on coming to World of Warcraft - Joystiq

Seems somewhat sad when the game needs a game within the game to keep things fun, but kudos to PopCap for not firing the lawyer guns. "Fromwiller developed the add-on as a method of killing time during long raids and farming sessions, but it wasn't too long before PopCap caught wind of the MMO mini-game. Instead of issuing a timely cease and desist, the casual gaming colossus hired Fromwiller to create a more polished version of the application."
