Kotaku has written an interesting article where they discuss if our newest Pokémon region, Kalos, is modeled after France or not. You should definitely give it a read!
[quote]As with past Pokémon games, the latest one, Pokémon X/Y, takes its visual cue from real world geography.
For example, in the last big Pokémon titles, Pokémon Black/White, the in-world map was apparently modeled after New York City. This time, the game appears to be modeled after France—though, as one Kotaku reader points out, the game’s official site says the region is designed after a star.[/quote]
