"Me neither! And it varies significantly by country, for me. Approximately how many countries does your world have?"

"Uh - sort of depends how you count. More than twenty and fewer than about fifteen thousand, probably."

"Wow. That is a large disparity. How would you be counting?"

"On the twenty end, it'd be - surface or routinely surface-contacting nations, most but not all populated principally by humans, that are countrylike in structure, mutually recognize each other's countryhood, etcetera. On the fifteen thousand end we start counting individual bands of goblins and pods of merfolk and certain church or monastic collectives and the occasional individual dragon and so on as sovereign in their own right, which might in a certain light be closer to the practical reality of how fragmented the world is, but would involve a lot of 'countries' partially geographically coextensive with each other, unrecognized by other countries as independent political units, and not undertaking most of the activities that are most paradigmatically country-like. Oh, and this is just the Prime Material plane, I don't know enough about the other planes adjoining it within the scope of my own world to even guess what their setup is like."

"Wow. That sounds chaotic. Wait, other planes?"

"Like the elemental planes and so on. I really don't know much about them."
