1. Ultimate Marvel vs. Capcom 3
Combined with the vanilla release and a lack of big titles in the first half of the year, no game soaked up more of my time than MvC3.
2. Portal 2
In my opinion, no one merges immersive, detailed worlds with solid gameplay like Valve.
3. Gears of War 3
Great campaign, great multiplayer, and a fun universe. This game merges everything learned from the other two in a super polished, fully featured package.
4. The Elder Scrolls V: Skyrim
OK, no lie...I haven't played this yet. I am terrified of it because I know how much I will love it and neglect everything else (judging by my Oblivion and Fallout 3 experience...so this is pretty much where it will land...hey it's my list, deal with it).
5. Assassin's Creed: Revelations
I can't get enough of Ezio and 'parkouring' around the past. And now with refined and still unique multiplayer.
6. Battlefield 3
The single player campaign and co-op were a disappointment. But only because the hype was too much!... it was still serviceable. But this is BF and I am here for the multiplayer. Honestly, I think BC2's felt better, but I think that is more of an issue of getting used to the changes. Still, I am eagerly awaiting the release of Wake Island, and frankly, no other multiplayer FPS touches the variety that BF offers.
7. Batman: Arkham City
The suprise hit of 2009 is back with a new, immersive open world. I wish there had been more innovation with the actual gameplay, but this is still a whole lot MOAR of the fantastic original. I can't wait to see what else Rocksteady has in store, but hopefully they will move on from the license.
Full disclosure, I am a total id fan boy. The choice to make the multiplayer a car combat game was puzzling though, and probably kept this game from reaching it's full popularity. But those who gave it a shot realized that it was actually quite fun. Regardless, the single player was much better than people gave it credit for: the world was very immersive and so, so gourgeous. I'd say, the best looking game of the year. Only the abrupt and frankly, HORRENDOUS, ending of the story kept this game so low on this fanboy's list.
9. Mortal Kombat
As part of the renaissance of fighters, MK did not capture my attention as much as Super SF4 or MvC3. However, this was still a very solid game that did one thing that no other fighter has been able to: An awesome and unique single player story mode. That alone deserves attention as a top 10 game of 2011.
10. Dead Space 2
I stayed away from the original as I did not like the 'feel' of the gameplay from the demo, and I'm also not a big fan of horror and jump scares. But, after so much buzz, I revisited the franchise in this sequel. The gameplay has been made to feel much more into a shooter and the horror was toned down. To me, that was a huge improvement which lead me to thoroughly enjoy a great campaign and universe.
11. Forza Motorsport 4
HONORABLE MENTION - Forza 4 was another sleek love letter to cars and racing games, and more than ever Turn 10 has been able to deliver a hardcore sim that is still somehow extremely accessible. Unfortunately, the fact that this game was largely just 'more of Forza 3,' kept it from my top 10. It did not, however, keep it from my 360's disc tray, as more Forza IS a good thing.
