What real-world locations do you want to see as regions?

It could be a country, state, region, island, whatever, they don't seem to have a format for choosing what areas get picked to be one next.

Personally I'm hoping for one inspired by the Carribean (to link Paldea and Alola), one based off Eastern Europe or the Middle East (to link Kalos and the Japan-inspired regions), and one inspired by another US state (to see what Unova's connected to)

Would love to hear your ideas! :D
