I play Counter-Strike, but I dislike Counter-Strike: Source, due to the fact of which it really has turned into a really noob game. Being of which, spraying a whole entire clip into a 5 man team, really doesn't strike my interest what so ever. If you play video games for graphics and everything CS:S would be your best bet.. if your looking for hardcore competition and actual skilled players CS 1.6 would be where you want to be. CS: Condition Zero, is basically... a medium in competition and graphics. It looks a bit better then 1.6 and the competition is a bit worse.
If you want to server hop with me, Mr. James.. You can add me on steam @ UnrealTorture.
