World of Warcraft, if it's half as good as it looks in the preview all over the web it will suck away my money, my soul and probably my personal life.
Fable, the only reason I have for buying an X-Box... And I'll probably wait until it's been reviewed to death (still sore 'cause of Black & White

).
Half-Life 2, and they better make it a more fulfilling experience than the Doom 3, darn that game was a let down. After a single hour of playing I could with 80% accuracy predict every and all monster encounters, thus killing the survival horror part of the game.
Warhammer 40K, contemplating this one, been beta tester from the closed fase on, but have been disappointed with the gameplay elements (specifically balance issues).
Looking back at this small list and the much larger Pen&Paper purchases wishlist, I'm torn between robbing old ladies or developing a gambling habbit to pay for it all. MMmm, maybe I need to open a poll on that one
