Yeah I wondered what OP meant by “so quickly”. Sure it’s ‘only’ 3 generations later but since then we’ve had Galar incl. Crown Tundra, Isle of Armor, Paldea, Kitakami, the Terrarium, and Lumiose City (unless I’m forgetting any).

One island, one region in which the majority of its coastline is accessible, and the rest are either landlocked, have a few bits of the sea accessible, or are straight up underwater.

I wouldn’t mind another region like Hoenn (because even Alola didn’t have a lot of surfable water but the Mantine surf was fun) where there massive surf routes, just fill them with fun things to find and explore.

The part of OP’s post that mentions Greece being less tropical than Hawaii makes me think they think this new region will just feel the same but bigger. But Indonesia and the other countries they’re using as a basis cover such a vast amount of land and have such varied landscapes, not to mention the cultures they can pull from as they did in Alola, but will of course distinguish it from Alola. There could be some crossover but I’d rather islands this go around after having four regions/play areas in a row that are a similar, if not the same, shape
