Heart Gold and Soul Silver were changed too significantly. The original Gold and Silver surpass it in almost every way. The music was raped, the gameplay is horrid, and they even changed the design of so many key locations. Honestly, if the music was just changed to be more modern, and they didn't rape the hell out of it along with the levels, the game would probably be perfectly fine. You can't tell me that the new music is anywhere near as good as the classic either.
