I don't understand why M2TW does not follow primo genitur fully so that Hans would be the Prince. I tried to give Hans Staufen as a consolation, but as Ignoramus pointed out that was against our character. Still, he is a Count at 16, which is something. Generally, I think titles - and settlements - should be earned to make them more interesting for role-playing reasons. But the Emperor's oldest son does deserve something as of right.
