Probably my biggest list, though the majority are really short:
Games I already beat, but beat again this year:
Scott Pilgrim vs the World- beat it with Ramona; now I just need to beat it with Knives and Nega Scott and the game's beat with all 6 characters (man, I love this game)
Resident Evil 5- finished the last hour of the game on my second playthrough that I held off last year
Games I beat for the first time:
Resident Evil 2- A/B scenario, which I was told was the non canon scenario, RIGHT after I beat the game.
Kirby's Epic Yarn- was in the last areas in 2010. Just had to finish it off
Uncharted 1- Amazing
Uncharted 2- Holy crap
Sonic the Hedgehog
Sonic the Hedgehog 2- finally finished my favorite Sonic game
Okami- Loved this game. I need to play it again
Streets of Rage 2
Hard Corps Uprising- beat it with Krystal. Will start my Bahamut playthrough soon
Turok 2: Seeds of Evil- huge disappointment. It would have been amazing as just an FPS if it didn't take 200 hours to go from point a to point b. It was just a giant scavenger hunt with amazing guns and shooting.
Dead Nation- bleh
LittleBigPlanet- awesome, but just plain cruel in the last levels
Backlog (3 games left until it's complete (2 games are now added since 2010):
Jet Force Gemini- I just need to sit down and play through this one day
Chrono Trigger- I take eons to finish RPGs. And the worst part is when I sit down to play it, I forget what I have to do and wander until I quit. Need to beat this game. It's so great.
Resident Evil 3- Got to the part with the trolley filled with the men with fake accents and Jill gives her billionth speech on how Umbrella is evil. I still can't fathom her stupidity in the game.
Pursuit Force- Just need to sit down and finish off the last gangs. It's kinda hard.
