Pokémon Ruby Version[a] and Pokémon Sapphire Version[b] are role-playing video games developed by Game Freak, published by The Pokémon Company and Nintendo for the Game Boy Advance. They are the first installments in the third generation of the Pokémon video game series, also known as the "advanced generation". After years of Nintendo being the sole publisher of the franchise in all regions, The Pokémon Company began co-publishing the games for the first time since the establishment of the joint-owned company. They 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. Remakes of the two games, titled Pokémon Omega Ruby and Alpha Sapphire, were released for the Nintendo 3DS worldwide on November 21, 2014, exactly twelve years to the date of the original Ruby and Sapphire release date, with the exception of Europe, where it was released on November 28, 2014.
