1. Portal 2
One of my favorite games of all time let alone in 2011.
2. The Elder Scrolls V: Skyrim
Another one of my favorite games of all time and probably the best RPG ever made in my humble opinion.
3. Dead Space 2
A good example of how to make a stellar sequel. Keep the good things awesome and bring even more awesome things to the table.
4. Batman: Arkham City
May possibly be my favorite Batman story ever told. At least in the top five.
The best Zelda game to come out this year.
6. The Legend of Zelda: Skyward Sword
If it were any other year this would be number one.
7. Gears of War 3
The perfect ending to that trilogy.
8. Cave Story
Not sure if it came out in 2011 but that's when i played it. It scratched my Metroid itch good.
This game stole so many hours of my time.
10. Star Wars: The Old Republic
If I had more time with it in 2011 it would have been way higher.
