You should have made this thread at the beginning of the year!

1. Starcraft 2
2. Metal Gear Solid 4
3. Gears of War 2
4. Resistance 2
5. and the rest are potentials since I have a 2 game gamefly account.

If Nintendo releases Zelda this year then It'll be game 3. Soul Calibur 4 and Tekken 6 must have online play to warrent a first day buy. LBP, FF4 DS and Too Human will depend on reviews and user feedback. Spore probably won't get released this year....and I'll wait to how far apart the console version of Fallout3 is compared to the PC version.

1. Resident Evil 5
2. Fallout 3
3. Fable 2
4. Star Wars Force Unleashed
