Best of 2010
I feel that Shadow Complex deserves a mention because I just got an Xbox 360 about 3-4 weeks ago and I wasn't able to play it last year despite wanting to. Not only was it worth the wait, it still completely blew me away. Insanely fun and addictive, I can see why It won Giantbomb's 360 game of the year. Shadow Complex is my 2010's 2009 Game of The Year.
