Joystiq: Let's face it, buying a game is just too simple. You don't want to just walk into any store and know that you'll get the same game you would get somewhere else. No, you crave complication. Sensing this innate need, Ubisoft has announced, via the Prince of Persia Facebook page, that those who pre-order Prince of Persia: The Forgotten Sands from GameStop will receive an exclusive new game mode. The offer, incidentally, applies only to the Xbox 360 and PS3 versions, so PC and Wii gamers are out of luck.
