I still have yet to buy this game, but luckily my roommate has it. MW3 ruined CoD for me, really. They're gonna need another CoD4 or MW2 innovation (maybe next gen consoles and/or new engine?) before I spend my money on another CoD.
Halo will still manage to drain my money I fear though. And I haven't played Halo since before Christmas I think.
Battletoads, Killer Instinct, GoldenEye, Perfect Dark, Jet Force Gemini, DK Country, Diddy Racing, Banjo, Conker. Rare, you will be missed.
