Brave trainers once again face off against wily rivals and hunt for rare, wild pocket monsters in this quest to put a stop to the destructive expansion of Team Magma and Team Aqua. Following a tradition established back in the later days of the original Game Boy, the GBA's Pokémon Emerald is, in essence, an enhanced version of Pokémon: Ruby and Pokémon: Sapphire, with many similar settings and features and the ability to link with either previous game. Emerald is also compatible with the other Pokémon releases in its generation, including Pokémon: FireRed, Pokémon: LeafGreen, and the GameCube's Pokémon Colosseum.
