Brink - I might get it.
Red Faction: Armageddon - I might get it.
Alice: Madness Returns - I just heard about it so I have no idea but probably since I love the first game.
Duke Nukem Forever - I might get it.
Dungeon Siege III - No idea, I might get it.
Dead Island - Definitely buy it.
Deus Ex: Human Revolution - I might get it.
RAGE - Definitely buy it.
The Elder Scrolls V: Skyrim - I'll buy it.
Mass Effect 3 - Hah! Nope, not until it's been 2 months and I've heard what people "really" think about the game.
Saints Row: The Third - Definitely buy it.
I don't buy games for the sake of buying games.
I'm very fastidious when it comes to gaming so if I predict that the game will actually be worthwhile then I'll buy them, don't exactly have a lot of money to just throw around.
So out of these the games I will buy are Saints Row, RAGE, Dead Island and Skyrim.
The rest of the games I will wait a month or two after it's release and then see gameplay videos and read fan/player reviews of the game to decide whether or not it sounds like they're worth getting.
Don't see how you could want every one of those games though.
Too many IMO.
