Half Life 2
I know it's a year too late, but after playing Half Life 2 all I have to say is wow ! wow ! WOW ! and W*O*W !!!
It's an amazing game !
The graphics are mind boggling, everything looks so real, you feel like you're actually there.
Top notch physics give it an even higher sensation of reality.
Excellent AI, both of enemies and friends.
Not too easy and not too hard to pass,
and a tantalizing story line.
Everything just comes together into a smooth and fun gameplay.
It undoubtedly sets a new bar for FPS games.
After playing CS 1.6 for a couple of years, and now playing HL2, Valve is definitely my favorite game manufacturer.
Here are some of my screenshots (forgive the low-end graphics card):
