Updated the OP with some slight price changes. Darksiders 2 is an exceptional deal at that price. Better yet, no promo codes required.
As a heads up, if there are any good deals next week I will be really slow updating them. I will unfortunately be required to spend many hours in Sanctuary with my friends so updates will be a low priority. What I am really getting at here is feel free to use the Wiki features next week!
Also: Don't buy Risen 2, it is a step back from the first game. It is riddled with horrible bugs and the most awful pop-in I have seen in a game. I can usually ignore all of that crap but it is quite overwhelming in this game. I also got a game breaking bug about 25 hours so I won't even be finishing the game it looks like.
