Eskimo: Just so you know, you don't need a CD at all, not even to install it. Being the Counter-Strike player that I am, all you have to do is download the Steam 1.6 client, and then you can download the whole HL series of games, including Day of Defeat and whatnot, for free. Yes, they still need a CD key, but getting that is easy. Walk into your good ole Wally World and.....well, nevermind. >: )
