Since I've actually finished some games now
The Elder Scrolls III: Morrowind - I finally beat it, it was my first Elder Scrolls and purest openworld experience as a gamer, and I've just recently gone back to beat it.
Mirror's Edge - Really short but really cool first person platformer.
The Darkness II - Solid story driven FPS. Not as cool as the original, but a successor that I never thought would happen and I'm glad it did. Also probably the most violent game I've played in some time.
Psychonauts - Since the Double Fine adventure stuff happened I've tried to catch up on my Tim Schafer backlog. This game is great. The concept is brilliant and brilliantly executed. It's like the perfect mix between a solid platformer and Tim Schafer's older adventure games.
I got Brutal Legend, Mass Effect 3, Thief II and several others in the pipeline.
