Pokémon Gold is a role-playing video games developed by Game Freak and published by Nintendo for the Game Boy and Game Boy Color. They are the first installments in the second generation of the Pokémon video game series. They were released in Japan in 1999, Australia and North America in 2000, and Europe in 2001.
The games introduce 100 new species of Pokémon, and follow the progress of the central character, whose name the player may choose, in his quest to master Pokémon battling. Both games are independent of each other but feature largely the same plot and, while both can be played separately, it is necessary to trade between these games and their predecessors in order to fully complete the games' Pokédex. The Johto Saga of the Pokémon anime is based on the new region introduced in the games.
Like Pokémon Red, Blue and Yellow, Pokémon Gold and Silver are played from a top-down perspective, or third-person, with players directly navigating the protagonist around the fictional universe, interacting with objects and people. As the player explores this world, they will encounter different terrains, such as grassy fields, forests, caves, and seas in which different Pokémon species reside. As the player randomly encounters one of these creatures, the field switches to a turn-based "battle scene", where the Pokémon will fight.
There are two main goals within the games: following through the main storyline and defeating the Elite Four and Pokémon Master Lance to become the new Champion, and completing the Pokédex by capturing, evolving, and trading to obtain all 251 creatures. A major aspect of this is developing and raising the player's Pokémon by battling other Pokémon, which can be found in the wild or owned by other Trainers. This system of accumulating experience points (EXP) and leveling up, characteristic and integral to all Pokémon video games, controls the physical properties of the Pokémon, such as the battle statistics acquired, and the moves learned.
