1. Dark Souls
Great minimalist story, fun action, and grueling challenges. This was everything I wanted from the sequel.
2. Portal 2
This could easily tie with first as this was as much fun as Dark Souls. I have mixed feelings on wanting another sequel or having this be the end of Glados and Chell.
3. Deus Ex: Human Revolution
I love cyberpunk and I love stealth games and this mixed the two into a very William Gibson style. There was little chance of me not enjoying this game.
4. Batman: Arkham City
The story isn't as strong as the original but the additions to the combat and the new play styles from Catwoman, Nightwing, and Robin make this a worthy successor.
5. Mortal Kombat
This game made me enjoy the single player story line experience of a fighting game. I'm still in awe.
6. inFamous 2
Though I don't believe it matches up to what I expected from the sequel to inFamous, it was still a great ride.
This game is such a joy to play when they're not throwing a challenge at you. When there is a challenge, you sort of have two choices: play with some friends or play the cheapest style possible.
I still can't get past how much I love the narration in this game and it's connections to the play style of Secret of Mana that I still miss. My problems with the game are that an isometric action game is rather difficult to play with a keyboard and mouse.
It's exactly what I wanted out of Minecraft but didn't get. I still need to spend more time in the world but I have no doubts of it being enjoyable.
10. The Elder Scrolls V: Skyrim
My first foray into the world of Elder Scrolls and though it didn't excite me as much as Fallout 3 it did have staying power. Its greatest downfall was probably the questionable combat immediately after playing Dark Souls.
