Oh damn, good question!
Let me see, I still have to finish Tales of Vesperia (damn this game is long), Infinite Undiscovery (only passed the first area, and I like the combat system), Blue Dragon (at disc 2, not bad so far), Far Cry 2 (I'm only at around 25%), Banjo-Kazooie: Nuts & Bolts (I have 39 jiggies, w00t) and Gears of War 2 (going to get all the achievements for this one). I might be getting CoD: WaW and Prince of Persia, both on 360, because of my bro.
I'm also getting quite a few PS3 games this Christmas: Resistance 2, Valkyria Chronicles and LittleBigPlanet.
I just hope to be able to finish them all! @_@
