have never had physical copy of a game that can be activated through steam, so dunno. i think it really doesnt matter, you can make a virtual copy of it anyawy, so it doesnt matter if you lose the CD
Actually, i had my mates TF2 cds (before it was F2P) and tried to activate it and obviously it didnt work, because the key was already used. so if it's used game, you cant activate it through steam.
You should be able to activate that, as it says "Requires internet access for Steam activation."
