I noticed that when playing as an HRE state the chance of having PU's through only royal marriages seems much higher? In about 150 years played as Brandenburg I had royal marriages all over Europe and got a total of 5 PU's. Am I right or were I just lucky? I left the empire tho after 10 years, it doesent seem to affect the chance or does it? I remember someone calling Austria PU heaven aswell, when i played them the chance to inherit a PU was great..
