>>50323972-Character graphics had a lot of bounce to it
-Made use of online and secondary gimmicks. Arguably an attempt to do online multiplayer in areas other than battle.
-Dialogue heavy game that shows Pokémon games can attempt storytelling, not the first game to do so but a notable case.
-It was interesting to see an attempt of "Americana" in the Pokémon world
-The music hit a lot of moods.
-The Pokédex was vast and forced players to try a different team as if were playing the series for the first time Also, like Sinnoh, has a smorgasbord of Legendaries.
-Ohmura's debut as a character designer supplementing Sugimori's designs for the player characters.
-Pushed the DS hardware further than being a glorified GBA as far as the Pokémon experience goes, having an active camera for battles and 3D structures were more pronounced for buildings and bridges, the game also wasn't shy about playing with elevation in an overworld Pokémon game much like HGSS.
