Yeah, unfortunately sunghost is too slow at letting us know about free things.
Getting a 404 error. Guess they've run out of codes. Unless the gift bundles include Dwarfs, it's no big deal that I missed it. Was just gonna grab a second copy for my secondary account.
EDIT: Now the page is back up with a note that the promo is over.
Not sure what the deal is, but I just got one, so they're not out of gifts yet. You have to log in at GameSpot and then "register" (verify your info and email) and then you get a link with a gift code.
