Hey guys, Gamestop is having a pretty decent PC Downloads sale going on at the moment. And they give you keys redeemable on steam, so you don't have to use their download client or anything.

Good time to pick it up for someone who you want to get into playing, or even for just a spare account to have in case you have a friend over that wants to play with you or something like that.
