I always end up buying way more games than I manage to play though, but I'll give it a try. RDR, DKC Returns, Mass Effect 2, Bioshock 2, and an embarrassingly long list of others are in my "shrink-wrapped collection"
Game of the Year
Super Meat Boy - I literally mashed at that game until my thumbs were ridiculously swollen... briefly iced them and went back for more punishment.
Best 360 Game
Alan Wake - Gameplay wasn't utterly fantastic but it was a lot of fun. I really enjoyed the story. The collector's edition was fantastic and really added to the value of the game for once.
Best PS3 Game
PS3 collected dust all year. So uhhh, Arkham Asylum 2 years straight baby! I can't wait until I get back around to finishing the God of War Collection so that I can play God of War 3. The 20 minutes of forced auto updates are going to be a riot!
Best Wii Game
Super Mario Kart Wii for however many years straight, baby!
Best PC Game
Starcraft 2
Best Handheld Game
Picross 3D I guess? I don't know, I like Flight Control HD but I have that on PC and it's probably not really a 2010 kind of game.
Best X-BOX Live/WiiWare/Virtual Console/PSN Game of 2010
Lara Croft and the Guardian of Light (even though I played it on PC)
Most Surprising Good Game
Lara Croft and the Guardian of Light - A friend gifted this to me and I just thought "Gee, thx bud"... never bothered looking at a review or anything, I'd been done with Tomb Raider after finishing the first one, which wasn't bad for the time... but I just never felt the need to play the series again. But Lara Croft was amazing co-op. Just a real joy to play.
Most Disappointing Game
Rock Band 3 - The launch was kind of botched, the website didn't work, the plastic pro guitar was delayed an extra month... the real pro guitar is still months away... the engine feels worse, they screwed up the practice mode. The learn an instrument mode is not an effective instruction tool, at least for learning anything useful about keyboards. Even the DLC has been all Classic Rock. I was so excited for this but I can't bring myself to even boot it up in the past few weeks.
Worst Game of 2010
Call of Duty: Black Ops - A really cheap feeling MW2 clone. A stupid plot and campaign, bad PC port, just all around bad. The very ending was just lame as well. A prompt to press 'F' to win the game. Give me a break.
Favourite DLC
Maybe this is more appropriate in the XBLA category since it runs standalone, but Dead Rising 2: Case Zero. I had a lot of fun for my five dollars there. I haven't gotten far in the actual DR2 game, but the setting there feels a little too samey with the mall type atmosphere. The small town in the desert was a cool change of pace. Haven't tried Case West yet either, maybe that one is even better? I don't know... but he's covered wars ya know?

Best News/Announcement
Call of Duty creators split from Activision/Infinity Ward. Asshat Robert Bowling FOUR ZERO ONE shit-eating liar and all around douchebag does not appear to be invited to come along. Great game imminent, CoD franchise forgotten.
Most Anticipated Game of 2011
I don't know, what's coming out next year? Gears 3? Respawn's game won't hit until at least 2012 right?
The Game Your Still Waiting to Be Released
Nothing that springs to mind. Also it's "you're"... c'mon man. There's typos, there's folksy message board writing with run on sentences and bad punctuation and god knows what else and then there are mistakes like that which could possibly cause me a stroke!
Best Non 2010 release you played for the 1st time
Fallout 3
Your Favourite Gaming Moment of 2010
That's a tough one, cheesing people in Sc2 is always a riot.... 38-0 round in MW2 (uhh, it qualifies as 2010 because it was on one of the DLC maps, bitch)... any number of satisfying A+ runs, bandage gets, or warp zones cleared in Super Meat Boy
