CS is my favorite game on the list, but you have to admit that Valve really needs some better anti-cheat software. I noticed that there are no games from the Battlefield series on the list. As far as best game ever, not best game with up to date graphics and features, but the best game ever would probably have to be BF1942, I mean come on, it changed the world of FPS for ever, and BF2 is right there at the top too. Now EA seems to be going downhill though.
