The steam version doesn’t require a CD-Key or a CD.
i tryed to use my CD key to put it on steam and it would not let me. so you are saying if you have COD4 on steam, they never mailed you a CD? that sucks. Anyone know if their is a way to install the CD retail version so that it does not require a CD in the disk drive every frickin time you go to play the game, this would be my best bet.
