Like what a lot people said, the singleplayer was done pretty well, but the multiplayer wasnt that great as CSS or TF2. Cod 4 had one-hit knife kills, overpowered perks like martydom and the three frag grenade perk. I also hated how players get rewarded helicopters and airstrikes for gettings several kills.

Cod4 is not my favorite game, but its still a good game because of the singleplayer.

Get Command and Conquer the First Decade, if you are not sure which C&C game to get.

The Orange Box, it would be a bad idea to get L4D now since L4D2 is coming out in a few months. Plus, the Orange Box is more worth your money since it comes with five games.

Pretty good trailer, I wanted to see more footage though.

Late 90's, first games I played was Quake, and Command and Conquer.

Half-life 2 of course.

1. Half-life 2

2. Team Fortress 2

3. Prototype

4. Call of Duty 4

5. C&C RA 2

Sniper, takes more skill than other classes.

Check on youtube they have some good strategies to use.

Tiberium series even though red alert 2 is my favorite rts, but not the series.
