Pokemon Ruby

Pokémon Ruby Version and Sapphire Version are the third installments of the Pokémon series of role-playing video games, developed by Game Freak and published by Nintendo for the Game Boy Advance. The games were first released in Japan in late 2002 and internationally in 2003. Pokémon Emerald, a special edition version, was released two years later in each region. These three games (Pokémon Ruby, Sapphire, and Emerald) are part of the third generation of the Pokémon video game series, also known as the “advanced generation”.

The graphics are a nice upgrade from the Gen 2 games (Silver and Gold).
The audio is decent, but I feel it is a little uninspired.
