I personally can't speak Spanish but because of the new Pokémon game hype I play many fangame recently and after diving from tips of the iceberg I realize Spanish community having pretty amazing fangame build skill. I personally can't speak Spanish but have friend who can speak the language. Most of the game have pretty interesting story and using gen 5 style Pokémon Sprite or the gen 5 overworld character and map Sprite or some fangame use both. If you guys decide to try I recommend Pokémon Africanus, Gadir and Opalo.
