Looking through your games, it looks like you aren't a fan of FPS's. Why not make an "FPS's are overrated" thread instead?
CoD4 is basically what you get when you mix Day of Defeat with Counter-Strike... instant kills, modern weapons. It's got some balance issues, but that doesn't stop it from being the best twitch-kill FPS this gen. The only major issue I have is it doesn't have split-screen online multiplayer (one reason why I still want Halo) - if that were added in it'd be my most played game this gen by far, and I've clocked over 100hrs on Brawl.
As for its single player, who knows. Like all FPS's, I tried it for a bit and quickly got bored. This is one reason why I find Valve so overrated (I also blame them for destroying CS), though I'll still eventually give Portal or Bioshock a try to hopefully spark some interest in the genre.
