Originally posted this on my IGN blog, but their new blog/friend system sucks and hence, nobody will ever see it. So, GiantBomb community, here you go:
 
I just pre-ordered Portal 2 on Steam, which comes with a free copy of Portal 1. That's nice and all, but come on... is there actually anyone out there who still hasn't played Portal? Well, if so, then this is your lucky day. The first person to respond to this post that has a Steam account (and doesn't already own Portal) gets my extra copy for free. Just reply here with a link to your Steam profile so I can make sure you don't already own the game. And of course, also make sure that your PC can handle it (system requirements available here).
 
Edit: Giveaway closed. Congrats to Lucifer.
