HG/SS... wonderful remakes Gamefreak, good job :3! They definitely improved the classic GBC games. The graphics were stunning and all the new features were great! For example, the follow me feature :D, how awesome it was to have my Pokemon follow me around.
Soundtracks became more epic and gameplay really was enjoyable. The only thing I would probably dislike was the change of Kris. Her design in HG/SS, wasn't what I really expected and liked.
