Probably none you mentioned actually :). However, I am looking forward to Operation Flashpoint: Armed Assault and BOB (if they're released this year).
Good call with Operation Flashpoint! definately looking forward to that
It will be interesting to see if NWN2 can emulate the success of it's predecessor.
There is also the tiny minnow that is Gothic 3 which might hopefully do a lot better than it's predecessors!
I'm really looking forward to Guild Wars chapter 2, with a bit of luck it will give me another 130 hours of play !
Also looking forward to Call of Cthulhu : Dark corners of the Earth, apparently it is hitting the PC this year at long last. Still holding out hope for that one.
Speaking of hope, still looking forward to Stalker, hopefully they will get their fingers out and we will see it soon.
Finally a game I am REALLY looking forward to is The Godfather for the PC, screenshots posted recently looked decent but the shadows were just blobs I noticed so they must be console shots. If this game is anywhere near as good as Mafia I will be a happy man !
