Hello, sorry for bad English. I am from Croatia and amazingly i had the same idea as you! Alltho i just wanted to make more provinces for Ex countries of Yugoslavia. I will send you picture of the last time i did the photoshopping, i used age of civilizations 2 map area, i only completed Slovenia and tried making some changes to the other provinces. I did not really add my attention to details, but i just wanted to try do something. Sadly i lost intrest in it and few months after i saw this. I am amazed dude. Do you need any help? I got map editor installed and got some experience with it. I also have rather enough experience in photoshopping to help with something like this. I hope i can get reply from you soon.
Best regards, Thompsonic 🙂
