All I have been playing lately is Marvel vs Capcom 3. I love fighting games, but I'm so bad at them. The grind to program every single combo combination into your brain and actually performing them in the heat of the moment. Ahhhh, it's a beautiful thing.
Also interested in getting Castlevania, Lord of Shadows here soon since I have some extra cash. But I have a pretty epic backlog at the moment.
Games I currently own and haven't played or have not finished playing: Assassin's Creed: Brotherhood, Bioshock 2, Dragon Age Origins, Fallout New Vegas, Dante's Inferno,Borderlands, Mirror's Edge, Army of Two, Lost Oddysey, Blue Dragon, Oblivion, Metro 2033, Mass Effect 2, Lost Planet.
I have a bit of an addiction for buying games lol http://oi53.tinypic.com/25k3aki.jpg
it's a tad ridiculous
