I will have to decide whether Serbia will be formable at some point, and this is the criteria I use for whether a country that exists in 1444 should be formable:
1. It defines the region and the name of the country would be adopted by a regional minor that united the region (England, France, etc)
2. There are minor nation/s or releasables with its culture that should be eligible to form it
3. The country has access to unique content (missions, events, etc) that would make the game more fun for aforementioned minors.
