Now On Sale Crusader Kings II & DLC’s at Amazon.com(r/CrusaderKings)
If you don’t have this game and want to get it, I recommend the Crusader Kings Pack for only $15. Includes CK1, CK2, and literally EVERY piece of DLC released to date.
I was able to snag this exact pack in January for $10, but $15 is a great price as well.
