Oh, you're right. It seems the title has been used since Johan III. Anyway, I always liked when you start off with a Vasa king after gaining independence. Keep it going!
I also didnt use : "King of the Geats, Swedes and Vandals" because it makes it seemlike Sweden is a shattered kingdom and I dont want that to be the case. Even if that was the official title it was largely defunct by the 15th century as Sweden was in a union under Denmark irl but in the game its not. Sweden is one nation and one pepole. Not 3
Hope this makes sense to you
