Its a shame that the map always turns out so barmy, It makes things like your Germany (which looks awesome) just look odd on the map. You should play 'World Police' and make the map look prettier. Also how much of Austriaaaaaaaah is cored?
I wish the AI had this thing called sensible expansion, wouldn't have to manipulate the map to make it look good. France and Spain actually looked pretty good too before they decided to fight hopeless wars and get Aragon/Flanders force released.
Austria seems to be more than half way cored... since most of those newer provinces to the east are huge in land area it is kind of deceptive. They have their Balkan provinces cored, and most of the former golden horde's 1399 starting zone cored. They inherited wrong culture Bohemia so there's a big chunk of non-core, and the timurid conquests were more recent.
