In my opinion, call of duty 4 is the best fps, altough all the games you guys said are really good, and maybe we can not say "this game " or " that game " is the best fps...

We can choose what fps is better following some aspects, and maybe one game is good when telling a story, but not as good in gameplay and vice versa...

Personally i like cod 4 a lot although all the other games you said are excellent :)

By the way, heads up for far cry 2 ;) eheh
