This looks fantastic. Take a peek at 1506 in the map progression and imagine being an English soldier in Stauffen (pretty sure that's Stauffen). To me it looks like the AI kicks AI ass when one AI has two fronts and the other only has one to deal with even if the AI with two fronts should have more than twice the army. It also seems prone to overexpansion so it gets huge very quickly when it starts rolling up an enemy country, doesn't defend well and a little guy in turn steals all the land again.
