- did you lived in that part of the world for 400 years to make propositions so preposterous like this?
His post was in the present tense. Don't be a lunatic.
The game lacks a cultural union for south slavs, so it is something useful to add. From a gameplay perspective it would just be a grand union of all these small cultures in the area. The region is tricky enough for the small native countries and it's not a rich area, so throwing the bone in a form of a cultural union is very worthwhile, and no, should not need to take >10 admin tech. Arguing that this area should have to wait longer than others because it took longer in our world is absurd, since our history never saw any possibility there - the region was far too dominated by Ottomans, Austria and Russia.
Of course, the difficulty creeps in when you also look at a lot of the nationalist sentiment of the region, made worse when many of the people with a raging nationalist agenda about their Balkan state actually pride themselves on it, rather than seeing nationalism as the infantile disease that it is. With this in mind, naming it something ahistorical like Illyria IS fine, as it avoids the whole matter, and catering to any one side would be awful. Personally I'm probably too much of a troll; I'd be naming it Kosovo, but then I don't rightly care what it's named.
