Amazon has a digital deals guy who hangs out on forums and everyone begs him for Steam keys so he makes sure he can get them when he can. Their customer service is great. I hope these $5 coupons we're getting are stackable in January.
The Arkham City DLC looks utterly uninspiring. Challenge maps and clothes for challenge maps and a tiny story DLC that I, so far, see unanimous disdain for. So I'm cool with not having a GOTY there.
