Of course beeing Italian and beeing Pokémon my favourite game series I'd love to have a region based off Italy but since the strange souvenir was first shown I always thought that Chile would be a great place as a setting for a Pokémon game (I speculated that the strange souvenir was inspired by Easter Island). additionally to Chile Perù would be a good setting aswell ! Other than that the United Arab Emirates or Australia would be spectacular settings !
