More Accurate Cultures

[Clownie]

My main historical interest is WW2, but one interesting thing I picked up was that Transylvania was predominantly Romanian, with some aggressive Magyarisation prior to the break up of the Austro-Hungarian Empire. To me, in EUIV terms that would mean changing the culture of the 2 southernmost Transylvanian cores from Hungarian to Romanian.

Some provinces also had a Szász majority.

The area was generally a clusterfuck and can't really be represented well in EU4. Romanian would be better than Hungarian, though.
