Game director Shigeki Morimoto aimed to respect the feelings of those who played the previous games, while also ensuring that it felt like a new game to those that were introduced to the series in more recent years.

The basic goal of the game is to become the best Pokémon trainer in both the Johto and Kanto regions, which is done by raising and cataloging Pokémon and defeating other trainers. HeartGold and SoulSilver take place in the Johto and Kanto region of the franchise's fictional universe, which features special creatures called Pokémon. In commemoration of the 10th anniversary of Gold and Silver, the games were released in Japan on September 12, 2009, and were later released in other regions during March 2010. The games are part of the fourth generation of the Pokémon video game series and were developed by Game Freak, published by The Pokémon Company and Nintendo for the Nintendo DS. Pokémon HeartGold Version and Pokémon SoulSilver Version are 2009 remakes of the 1999 Game Boy Color role-playing video games Pokémon Gold and Silver, also including features from Pokémon Crystal.
