Welcome to the guild, Malach!

As far as I agree that the Aegaen Sea and Turkey with Istanbul is an intruiging coastline, I would not advise to use it in a CRPG. It's too recognizable. My first thought when I looked at the map before I even read your post was "Hey, that looks like Greece and Turkey upside down!". Hit me on the head if I'm wrong, though.

Again, I see the appeal to use this. But even if you just want practice, I'd still recommend drawing your own coastlines. If you've got a backstory for this that ties in the real geography, though, go ahead! That could get interesting.

If you'd draw your own coastline, you could also achieve a sharper (for lack of a better word) outline, since the small islands aall look like green dots. I guess that happened when you copied the original imag and rescaled it.

Sorry for being such a harsh critic, hope I didn't spoil it for you!
