These are the games I look forward to the most in 2008, in no particular order:

Grand Theft Auto IV

Fallout 3

Banjo Kazooie 3

Gears of War 2

Civilization Revolution

Mario Kart Wii

Super Smash Bros. Brawl

Starcraft II

In addition comes any Mass Effect-sequel, though none are announced yet. In fact, it would probably be THE game I looked forward too. Man, I loved that game :)

There are other games I am very interested in too, but these are the very top.

And yes, I bought a Wii! Wohoo
