Pokémon Ruby and Sapphire

Pokémon Ruby is (together with Pokémon Sapphire) the first Pokémon game for the Game Boy Advance. It features greatly enhanced graphics, dozens more Pokémon to catch and train, and an entirely new game world to play in. It was later followed by Pokémon Emerald, an enhanced third version of Ruby and Sapphire featuring improved graphics and an adjusted main storyline.
