A special sale pack I found that I thought was worth mentioning, this one from amazon digital. A Paradox pack:
A lot of good stuff for about $12.50 - Crusader Kings 2 (worth it for that alone IMO), Magicka collection, Sword of the Stars 1 (complete), SoTS2 (which is getting much better and playable), and Victoria 2. Really good buy, but I'm thinking its today only. I believe that Magicka, SoTS2 and Crusader Kings 2 are all Steam activations.
