I have a question: With Crusader Kings, Europa Universalis II, Victoria and Hearts of Iron II it was possible to import the saves and in this way play through 1000 years of History. Is this with CKII, EUIII, VII and HoI III also possible? When yes how? I don'T have the other games so I didn't do it ever. Can someone help me?
Yes it is possible it is called "paradox mega campaign" some people have done it with CK > EU3 > VIC2 > HOI2 or HOI3, but it is also possible on CK2. I'm doing it right now (I'm finishing CK2 as Hungary) there is some convertors, but they don't perhaps work as they should. Best way is to learn mod every game which is needed like I do, but yeah I could help you convert your game manually if you add me on steam http://steamcommunity.com/id/Chlodio
