That last pic and the pic of the tree are amazing! My expectations for this games graphics just went up a couple of notches!
I'm really dying to play this game but I can't add any more games to my queue until I've cleared out a bit of the backlog!
I finally finished Oblivion (truly amazing experience) and i'm currently tackling C&C3. I also need to finish Lost planet which I must be at least 70% through and then make a start on Assassing Creed and the PC version of Gears.
Once i'm done with those, I'll pick up Warhead, GTA4 and Farcry 2. I can't beleive some people think there are no good games on the PC. The sheer amount of amazing games out there right now is incredible!
