First of all i'd like to thank everyone who made this list, it's a great list and, thanks to faust, really nice to read.
I have played a lot of games mentioned in the list, some i didn't play, but i could understand why they were in the list.
Except Guacamelee! I've played the game and yes, it is funny and original, but, IMO, not a, how do i say this, "full-worthy" game.
I mean, it's too short and the graphics look like a cheap saturday-morning cartoon, that fits the game however and is not bad, but not good enough for a high quality list as this.
I just tell you the truth about my opinion and believe me, i rather play Guacamelee! then MGS4 or CoD, which i don't play, but it just doesn't fit in the list. Even a move-game would be better.
But enough about that, the list is a pearl nonetheless, i would personally add Diablo 3 and Beyond: two souls. I'm into FarCry 3 right now and that is a beauty indeed.
