Re: most wanted game for this year ?

In terms of must-buys I'll be looking at Dead Space 2 (although EA are non-commital on a release date atm) and Bioshock 2.

Depending on reviews: AvP, Dante's Inferno, Prince of Persia and Heavy Rain.

Dark Horses could be I Am Alive and Transformers: War for Cybertron.

Looking to the end of the year of course COD: Vietnam.
