:/ That just seems silly.
What if you uh....preordered the steam version...at gamestop...? >.>
You can't. It doesn't work that way. All you can do at Gamestop is buy prepaid Steam cards to buy things yourself.
I preordered the steam version at GameStop. They gave me the receipt and told me when I come in to get it they would give me a code for it on the receipt they would give me then. Im looking at it right now.
