Yeah, I'm with you there, my backlog of unbeaten games is growing far quicker than my list of beaten games. Plus I now own a PSP with.. ehem.. *unofficial firmware* so I have a basically endless supply of games to play on that front.
I'm really going to tone down the amount of games I buy this year. I'll probably be buying Mario Galaxy 2, Monster Hunter 3, Tales of Graces, Dead Rising 2, Fragile, and that seriously might be it, at least for day one purchases. I bought way too many games last year.
