Developer: Game Freak
Released: 1999–2001, Game Boy
Pokémon Gold and Silver were the long-awaited sequels to the original Red, Blue, Green, and Yellow that started the whole Pokémon craze. Being released as two of the first games for Nintendo's then-new Game Boy Color, Gold and Silver benefited from the new possibilities of colorful Pokémon and maps. Due to the prolonged development time, there are many remnants of early content for nearly every Johto city along with some unused events and debug menus.
