Playing Shift 2 Unleashed right now. Probably about 75% done with it. Next up is Assassins Creed 2, followed by God of War III and then Uncharted 2. I've already got The Elder Scrolls V: Skyrim pre-ordered, but it's not coming out until 11/11/11.
Some others I might pick up this summer:
- Mass Effect 2
Deus Ex Human Revolution
Red Faction Armageddon
Far Cry 2
Have to see how much time I get, I may not get around to all of those.
