I just rented a copy of G.I. Joe: The Rise of Cobra (on PS3) as I was on my way home from class... I was shocked as hell that it was even in stock on the day that it launched in game stores. Granted, I am not expecting to be blown away by this game, but I'm a long time fan of the comic book & cartoon series, going all the way back to the 1980s... so I wanted to at least give it a try for myself.
Also, I have been playing Fat Princess as of late... I think it's a damn solid game for only $15.
