5)Wii Sports: For me it wasn't as revolutionary as everybody says it is, controllers were really imprecise and I stopped playing after some days
4)LittleBigPlanet: I don't why but I didn't enjoy it, didn't like the level design and the level editor was hard to use. But I think LBP2 improved everything that I didn´t like about the first
3)The Walking Dead: The characters and story are great, but I was disappointed because the decision really don't affect the game, you can chose some character's fate but overall the story was the same.
2)Arkham City: I remember reading "this game will make you feel like batman". But the "city" size is disappointing, the main plot was not as good as the first one, I never felt the city was alive. I think is a good game but I like more the first Arkham
1)Super Mario Galaxy: This game is excellent but is far away from being the best game of the generation, I don't think it revolutionized plataformers
