Here's version 7. In a nutshell I cleaned up the Aegean and added the river where qwert wanted (I hope).

Still need a better number of territories. Is there any way to carve more regions out of this map? I could split Trakya into two provinces, probably, and maybe parts of Romania and Bulgaria, but not enough to hit 55 (54 without Kosovo) territories, I don't think...
Thoughts?
Also, still need better names for the territories named after capitals (Tirana, Skopje, Podgorica, Sofia, Bucuresti)
So, things to do, roughly in order of importance to me:
1) Decide on the number of territories. This is huge.
1a) Keep Crete? Should be decided somewhat soon.
2) Decide on impasable locations and then finalize bonuses
3) Graphical tweaks, esp. with regard to the legend and the title.
