I see a bunch of stuff about playing the paradox titles in sequential order as a canpaign. Starting with a version of Crusader Kings, then taking that game and bringing it into Europa Universalis, then Victoria, then Hearts of Iron. This interests me but I can't find anything on how and which versions work together. Is this still possible and if so, which versions work together? I've spent hours trying to find information on this and not had any luck.
Thanks for any help!
