Hey! Map looks really nice, and I'd surely play this one very often, but the names there needs some fixing
I'm a Turkish, so can help you with them
First of all, its Istanbul since 1453
No more Constantinople
We buried that name next to Byzantine )
Brusa - I think you meant Bursa
Trabizon - Trabzon
Angora - Ankara?
Erzerum - Erzurum
Diyrkablr - Diyarbakir
Kenia-Antep = Konya, Antep
Smyrna - Izmir
Gallipoli (its ok actually, cause this is the English version but if you wanna put Turkish version) - Gelibolu
Andrianople - Can't understand what you wanted to say there
My point here is, if you wanna put 1914 Ottoman Empire status, you shouldn't use Latin versions (or Greek), you ought to use Turkish ones.
By the way, in 1914 Kars was in the hands of Ottoman Empire, we lost it later (then took it back)
Just to let you know
Other than that, you can arrange the continent colors with bigger difference... Can't find the exact word, but right now they look alike, would be better if you use different colors in Anatolia at least..
And one question, Vilayet's give bigger bonuses or what? If not, I think you can remove the sign V?
Thats all I can say, I must say it looks very good and I would be happy to play it
