Yea I'm a bit late to the party. But I got COD4 for the PC for xmas. Great game. Loved it. But it was over too quick. I finished it in 3 evenings.

My 2 complaints about the game, 1) It's too short. Sure there's the multiplayer, but I'm not that interested in that. I might try it, but I like the single player. 2) There are some parts of the game where the bad guys just respawn and you never make progress. Which is cool if you just want to waste ammo and take out bad guys, but once you figure out that you can make it through the scene without firing a shot, it gets kind of boring. All you have to do for some parts is just "move up". Stay hidden enough to keep from getting shot and it just works itself out that the bad guys behind you are all dead.

Anyway, great game, hope theres some patches that add some more levels or something. Doubt it but hope for it. Maybe an expansion pack or something.

Game is stupendous, I just want more of it.

For reference, I'm using an AMD X2 4000+, 2gb ram and a 7600GT. Took the default quality settings, 800x600 and most things on normal or medium. Whole game was very smooth, no hiccups.
