Theres just one problem with playing Half-Life (The SP Game not its Mods) without the cd. You miss out on all the great music the developers made for the game. Dont know if its possible to copy the music files from the cd to the hd, but damn you enjoy Half-Life alot more with the music.
Anyways, I bet you dont care about the SP game of Half-Life anyway, you just brought it to get access to Counter-Strike.
