I was just wondering whether governor titles are tied to culture or government system? I remember in EU:Rome that your governors were still called chieftains even when you reformed your government and it was the same with pagans in CK2. Personally, I'd prefer kingdoms to call them Governors or Satraps (depending on the part of the map they are in) as this makes them sound a bit more civilised imo, but it's just a personal preference and I was curious to see what Paradox's plans were.
