In Pokemon HeartGold and SoulSilver, a special "MICHINA" Arceus was distributed at Toys R Us stores. This Arceus was first interesting as it knew three moves it normally never can learn: Roar of Time, Spacial Rend, and Shadow Force, which are interestingly the signature moves of Dialga, Palkia, and Giratina, respectively, the three dimension-governing Pokemon Arceus was claimed in Sinnoh-region lore to have created after the universe so as to govern it. The Arceus would be able to take you to the Sinjoh Ruins, "Sinjoh" being an amalgamation of the words "Sinnoh" and "Johto" (since Arceus originally was Sinnoh-native, and HG/SS take place in Johto): there, you can find three Eggs and take one, which will hatch into a Level 1 Dialga, Palkia, or Giratina.
There is an event coded into this game in Ilex Forest. If you bring a specific Shiny Pichu there that was distributed back in 2010, you can go to the shrine in the forest and find a Spiky-Eared Pichu. This is a reference to the Pokemon movie Arceus and the Jewel of Life in which you can see a Shiny Pichu befriend a unique Spiky-Eared Pichu. This Spiky-Eared Pichu can understandably not be traded to Pokemon Diamond, Pearl, or Platinum as the event hadn't even been conceived then. However, what is more confusing and as-of-yet unknown is why the Spiky-Eared Pichu cannot be brought to Pokemon Black/White, later-released Pokemon games, and even more confusing as to why Pokemon Black/White 2 cannot have it, for there was ample time for it be coded in between 2010 and 2012. This makes the Spiky-Eared Pichu the only one Pokemon from the DS era that cannot be brought to the 3DS games.
Pokemon HeartGold and SoulSilver are the first games that show the influence of Nature on a Pokemon's stats: in their Summary screen, if the stat is lowered 10% by Nature the stat's name is blue, and red if it is raised by 10%. This later became tradition for the series.

Pokemon HeartGold and SoulSilver are notably the remakes of the GBC Pokemon Gold and Silver games. Obviously, this comes with a number of changes, although much of the formula remains the same. However, Game Freak did make one special change to this: your Pokemon can now follow you in the field. This is much akin to the style of Pokemon Yellow in which your Pikachu will be able to follow you around: in fact, Pokemon Yellow (not even G/S/C) is the only prior incidence of this!
