So, outside of the Caucasus region, the Balkan region is pretty much the only region of European universally agreed upon to be underrepresented now. So here is my idea for a Balkan DLC. Keep in mind, this would be after a Caucasus DLC that introduces a new Balkan architecture set for the Bulgarians and Byzantines, and some of the new civs would have the same thing.
New Civilizations:
- Albanians (Balkan architecture): Represent medieval Albania, including the Principality of Arbanon, the Kingdom of Albania, and the League of Lezhe.
- Croatians (Balkan architecture): Represent the medieval Croats.
- Serbians (Balkan architecture): Represent the Serbs, obviously.
- Vlachs (Eastern European architecture): Represent Wallachia and Romania, including the Transylvania region. Their unique castle is Bran Castle. Spooky!
New Campaigns:
The Vlad Dracula campaign is changed to be for the Vlachs instead of the Magyars and Slavs. The initial scenario is still for the Turks.
- Skanderbeg (Albanians)
- Tomislav (Croatians)
- Vlastimir (Serbians)
- Matthias Corvinus (Magyars)
