Ahh my speciality compute games!!
F.E.A.R is the best 3D shooter I have ever played. Incredible! Amazingly awesome. The game was worked on by the dude who did the RING the movie. Its creepy and gory and awesome. One of the best looking games ever. And it has the bullet time slow mo! I just beat it and i'm pissed that its over!!! I wanna play more.
However, if you don't have at least an amd 3000 or a p4 2.8 ghz and a pretty good video card then you will be miserable.
Quake 4 is decent tons of action good looking but not as good as F.E.A.R
Sid Meiers Pirates is pretty fun if you like sim games..
Far Cry is sick, Doom 3, Call of Duty 2 just came out and I'm waiting for my copy
The new need for speed looks cool but I'm not sure when it comes out. Soon I think.
I recommend FEAR though if your comptuer can handle it. Download the demo... If you can't get it to run as well as you want then don't buy the game.
Anyways I love PC games !!
