[7] In 2009, on the 10th anniversary of Gold and Silver, remakes titled Pokémon HeartGold and SoulSilver were released for the Nintendo DS.

Like previous installments, Pokémon Gold and Silver are played from a third-person, top-down perspective, 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.

[16] Opposing him is his mysterious rival, a boy who stole one of the other Pokémon from Professor Elm and regularly challenges the player to test his strengths.

[13] The player also encounters the villainous Team Rocket, having reunited to seek out their previous leader Giovanni to return the group to their former glory.

[12] Eventually, the player thwarts Team Rocket once and for all and defeats the Elite Four and the Johto League Champion on Indigo Plateau.

[21] Gold and Silver were first publicly showcased at November 1997, Nintendo Space World Expo in Japan, becoming the most popular exhibit at the program.

Other additions that were shown included Pokémon breeding, held items, an in-game gadget known as the PokéGear, a real-time internal clock, and backward compatibility with the previous games in the series.

[22] During an ABC News interview, president of Creatures Inc. Tsunekazu Ishihara gave insight into the brainstorming process for developing new Pokémon species.

The first official event offering Celebi was Nintendo Space World 2000 in Japan, in which 100,000 attendees would be awarded the rare Pokémon.

[24] Ishihara stated that Gold and Silver started development right after Pokémon Red and Green were released in Japan.

Satoru Iwata, then the president of HAL Laboratory who would later become Nintendo's CEO, helped the team by developing new tools for compressing the Pokémon graphic code.

[27] These ROM images were only rumored to exist until they were anonymously posted on the "Pokémon Reverse Engineering Tools" (PRET) Discord server in May 2018.

[27] Earlier in May 2018, Pokémon artist Atsuko Nishida revealed that the popular creature Pikachu was originally supposed to have a third evolution, named "Gorochu".

Matthew Byrd, writing for Den of Geek, stated that a lot of design work had gone into the Pokémon that were eventually cut, suggesting that Game Freak might have taken them out during the testing phase due to balance issues.

[34] In addition, an officially licensed Pikachu-themed Game Link Cable developed by Kemco was set for release in Japan on November 18, 1999.

[36] However, they were soon forced to cut the first shipment number in half following an earthquake in Taiwan, which Nintendo claimed had damaged their cartridge manufacturing facilities.

[38] To further promote the games, Nintendo modified five Chrysler PT Cruisers to resemble the new Pokémon Lugia and had them driven around the United States.

[39] The television series Pokémon GS, based on the games, was announced to be a part of the fall lineup on Kids' WB.

[44] In May 2000, Nintendo announced the official North American release date of Gold and Silver would instead be October 16 of that year.

[1][46][47][48] In North America, Nintendo started accepting pre-orders for the games in August;[49] a CD-ROM was available as a pre-order bonus that included clips and music from Pokémon the Movie 2000, screenshots from Pokémon Gold and Silver, a Pokémon-themed desktop wallpaper, an offer for a Nintendo Power Player's Guide, and Pokémon-related trivia.

[57] Pokémon Gold and Silver were met with critical acclaim, with many saying that the extended length of gameplay and the new features were valued additions that kept the sequels as interesting as the original games.

[8] There was particular praise given to the innovative internal clock feature, with Frank Povo of GameSpot, noting: "The first major addition to Pokémon GS is the presence of a time element...

"After playing the game dozens of hours, I really can't think of a bad point to make about Pokémon Gold and Silver.

Nintendo and Game Freak have tweaked the original and built a sequel that's long, challenging and tremendous fun to play.

[69][70] The commercial success was expected, as Peter Main, the executive vice president of sales and marketing, stated "There's no question about it; kids love to play Pokémon.

[72] In Germany, Gold and Silver received two Double Platinum awards from the Verband der Unterhaltungssoftware Deutschland (VUD) for sales above 800,000 copies by 2002.

[81] Commercially, they are among the best-selling Nintendo DS games of all time, with combined sales of 10 million units as of July 2010.
