We think Pokémon Omega Ruby and Alpha Sapphire are the perfect games to bring back the colored game cards because they are the remakes of the last original editions of Pokémon wich had colored cartridges (Emerald was a third version and FireRed and LeafGreen were remakes).
Español: Como todos los fans de Pokémon saben, sobretodo los mas veteranos, los juegos de las tres primeras generaciones de Pokémon disponían de cartuchos coloreados según la versión que fuese.
