In Victoria 2 Balkan demographics are kind of off. During the period of the game Albanians were kicked out of what is today Southern Serbia. This was known as the Nis Migration. Also Vlach, Morlach, and Aromanian populations are very under represented. There are also way more Christians(Orthodox,Catholic)in the Albanian inhabited lands at this time. This time period being when a big percentage of Albanians actually started converting to Islam. And the Bektashi Shiites are also no where to be found. I hope the Balkans will be fixed and flavor events will be added to the region as there is so much potential. Hopefully Victoria 3 will fulfill this and fix even more regions.
