Imagine getting the prestige edition. That would be $180 (game and maps) gone into Robert Bowling's wallet. Talk about a waste... I'd much rather give $180 to Josh Olin (Community Manager of Treyarch).
Right now, I spent only $60 on games made by Infinity Ward (don't have CoD4 or any map packs, just Mw2) and that's overpriced already just because of how awful the game is.
