1. The Walking Dead
Just amazing. Never read the comics, don't care about the TV show, the only zombie movie I like is Shaun of the dead, but this game just hooked me deep.
I did lose my save after episode 3, got sidetracked and played through the whole thing after 5 came out, and that was a pretty terrible idea though.
2. Virtua Fighter 5 Final Showdown
Best fighting game ever made. Perfectly balanced, easy to pick up, more or less impossible to master, but luckily the training modes are the best I've ever seen in a fighting game. Also it has Shun Di.
3. Mark of the Ninja
One of the best sneak'em ups ever made, great level design and really smart about giving you all the information you need to succeed.
4. XCOM: Enemy Unknown
Tactical turn based strategy (the best kind of strategy) with some fun base management thrown in. Most pleasant surprise of the year by a mile. Even the gamepad controls work great.
5. Far Cry 3
You can run over sharks with jetskis.
No game in the last couple of years managed to make me feel as dumb as fallblox does. And I love every second of it.
7. Mass Effect 3
The internet overreacted. This is a pretty great game.
8. Dragon's Dogma
Some annoying things like running back and forth through a mostly empty world fighting the same enemies in the same spots over and over and some of the best artificial stupidity I've seen in a long time with the pawns, but still a lot of fun, mainly because of the fantastic combat system and some pretty great enemy design.
I love a game that gives me an area, a goal and a bunch of systems and sets me loose to poke around and do as I see fit. Great fun, and they actually made first person sneaking and platforming work, which is no mean feat.
10. Assassin's Creed III
The ending is dumb as hell, but the stabbing dudes in the face and neck parts are great and the multiplayer is still pretty fantastic. Also naval combat is way more fun than I thought it'd be.
