Pokémon Sapphire

Pokémon Sapphire puts more emphasis on water routes and underwater Cave of Origin sequences than any other Gen 3 game. This randomized version populates Hoenn's seas and surfing routes with anything from the full Gen 3 dex. Sapphire's version-exclusive Pokémon like Lotad and Seviper are shuffled in alongside everything else.

Sapphire has more water routes and underwater sections than any other Gen 3 game, making it the best base for players who want variety in their randomized surfing encounters. With version exclusivity gone, Sapphire's normally Blue-exclusive feel disappears — the full 386-Pokémon Gen 3 pool is fair game across every route, surf spot, and dive area.
