Second for HG/SS. It had everything G/S had, which was solid to begin with, and added elements up through 4th gen I think. You get two regions, a huge pokedex, weather and day/night cycles, phoning the gym leaders for rematches, classic graphics before the 3ds. It has a all the classic Pokemon elements without all the clutter and limits of the new games.
