I have decided to add all Seterra quizzes to the leaderboards. I probably will and the rest like South America and that soon. Hopefully you all like the new categories.

Will the 193 UN Memberstates quiz be added soon as well?

Yes. I will add that soon

The name of the categories is ambiguous. According to the main page https://online.seterra.com/en it should be the following:

The U.S.: 50 States Africa: Countries Asia: Countries Europe: Countries

btw, website/wiki still links to the US game

I don't think it really is needed to change the tities as people can tell what it is and adding it wouldn't make too much of a difference. Also I changed the link. Thanks for that.
