Thanks, now, second question: I want to form the Roman Empire in my CK3 game, and at the right time (1444) convert it to EU4. Now, is there anything special about it if you do it? Like, if you pass the already reformed Roman Empire into EU4, the roman culture would be the only one in my Empire? Or it just works like any ordinary custom nation? I ask because if you create the Roman Empire in EU4, all provinces will turn to roman culture. Something like that also happens if you bring it back in CK3, and then convert it to EU4 from there?
