you can add more, you don’t have to make them all at once. I would recommend making the quizzes and adding them to the series in a batches of 3-5 so that you can make announcements about it.
Eventually it goes up to 10 per day, if "certain quality metrics are met"
There are different interpretations as to what the "certain quality metrics" are, but the most correct one seems to be when your quizzes start to get auto-approved
what if you made a "non-countries according to jetpunk" series where it's this same concept but instead of about places considered countries by jetpunk it's all the ones that aren't, like north cyprus or palestine or niue (it doesn't have to necessarily actually be considered a sovereign country by some other governing body it just needs to not be considered a country by jetpunk)
