Honestly, I'm surprised they went for Spain. Of course it is an interesting choice for a Pokemon region and I can see why they picked it, but in the last three generations we've had two European-themed regions, Kalos and Galar respectively. Kind of feels like they're only interested in the US, Europe and Asia (or more specifically Japan, but that one is obvious choice since Pokemon is Japanese). Why not put a region in South America or something. Hell, if the region is in South America you can do a whole thing with Mew since it was originally found in Guyana according to the Kanto games.
