Looks like Amazon wants in too. They’ve got a sale on Paradox games also. A bunch of Paradox games are on sale for 50% off. You might want to buy from here if you’ve got store credit or something. I actually have some for taking surveys.
Magicka games and the DLCs are 50% off. The game uses Steamworks so it will require Steam. This is pretty much the same sale that’s going on at GamersGate and Impulse.
