Breeding was a natural integration to the formula and is perfect for enhancing the multiplayer aspect of the game to get unique egg moves to share with friends.
Dark and Steel types are seen as natural additions to the original games themselves with things like the Magnemite line taking on the new type
Game clock enhances game's worldbuilding and became nearly a series staple

It's hard to find things that Gold and Silver didn't do right in all honesty.
