Pokemon HeartGold & SoulSilver
Of all the Pokemon games that released on the DS, HeartGold and SoulSilver might be the most beloved. They were remakes of the second generation games Gold and Silver with plenty of new features and quality of life changes.
In fact, many of the additions in this remake are features that fans have been begging Game Freak to bring back to the series ever since. Pokemon following the player in the overworld, for example, had been a wildly popular request until it was brought back for the Let’s Go titles (and subsequently abandoned once again in Sword and Shield).
HeartGold and SoulSilver used the DS’s Nintendo Wi-Fi Connection to interact with other players of not only the same game but also with players of Diamond, Pearl, and Platinum, which had released a few years prior. The game was bundled with a Pokewalker pedometer, which interacted with the game through the DS’s infrared technology.
Because of all of the improvements from the original games, HeartGold and SoulSilver were viewed as remakes done right, and arguably the best Pokemon game to date.
