Hello! I just picked up my PC copy tonight and came home hoping to get the game installed before going to bed. So I slap the DVD in and go through the process of entering the validation key and all that, and then Steam shows me that I am downloading the game. Why is that? If I wanted to download the entire game off of Steam, I would have purchased it that way. I can see the big .SID files on the DVD, so why can't I install those instead of waiting who knows how long for this download? Is there a way to do it?
