I would like to know the size of superhuman populations in your game worlds. And why did you choose those numbers ?
There is a question in my mind; how would the size of superhuman population effect the world?
One superhuman in a million people seems suitable for a classic superhero setting, where they are rare and mighty. 1 out of 50k being a low powered superhuman seems proper for a x-men like setting where metahumans are downtrodden.
I would appreciate your ideas on population issue.
