Two more from this year you might want to consider:
- Diablo III: Evil Edition: a lot of fun. also a lot of replay value with the multiple character classes and difficulty levels.
- South Park: The Stick of Truth: I think this is some of the best material Matt and Trey have written in years. It's bolstered by some solid RPG mechanics, similar to the Paper Mario games. I enjoyed it a lot the first time around but I'm not sure if I want to play it again after seeing all the jokes once already.
Also think about: Fallout 3 & New Vegas, The Witcher 1 & 2, Shadowrun: Dragonfall - Director's Cut, Rogue Legacy, Persona 3 & 4, Bastion, Deus Ex 1 & HR
