For anyone who is interested, this is the map of europe about 1380 (hopefully the upload worked), with me as Italy.
My main impression from it was that the HRE is way too powerful, even with Bohemia goone pretty quick, nd my own independence by about 1200, they still took most of France, Spain and Norway, and had primogeniture by 1150, and the salian dynasty is still incharge.
The Byz Empire was supremley stable, still with the Doukas dynasty, and has started to expand against the hordes.
Russia, though conquered by the golden horde, won independence quite quickly.
England and France however where FUBAR, which suggests to me that Empires are too stable whilst kingdoms are the unstable.
Aside from that, the papcy and venice are both pretty redundent entities and proably need a good DLC or something (adding maybe the papal curia or something).
My main feeling is that the HRE should be limited in how much it can expand beyond it's de jure lands, which would seem pretty historical to me (Guelph and Ghibilines for example).
