What else should I add? What are some of the most evident lacking families or nobility characters? Should I add every single state that ended up being Germany or Italy? In which moment it starts to be overwhelming? But which parts are often overlooked and should be featured? Also, I will start as soon as possible with Asia. There which countries, families and monarchies should be to be fairly complete?
Thanks a lot for your time and attention.
