Pokemon Emerald Version is the definitive 'Director's Cut' of the Generation III Pokémon games. Released after Ruby and Sapphire, it combines elements of both stories. Players must stop both Team Magma and Team Aqua from causing a climate catastrophe, requiring the intervention of the legendary Sky High Pokémon, Rayquaza.
Emerald introduces the 'Battle Frontier', a massive post-game island with seven unique battle facilities that test the player's mastery of combat mechanics. It also adds animated sprites for Pokémon in battle (a feature absent in Ruby/Sapphire) and allows players to re-battle Gym Leaders. It is widely considered one of the best Pokémon games ever made due to its extensive content and challenge.
