Similar story with me, I love being way behind on games. Over the last few months I have got through some great games from a few years back - Uncharted 1 & 2, Batman - Aslyum & City, Red Dead Redemption and Mass Effect 2.
I have a PS3 at the moment. My plan for 2012 is to buy an Xbox (next month) and purchase the Gears Of War series, Halo and Forza, can't wait.
