Whats the best Pokemon Game

It depends on what system and generation your looking for, for Kanto (gameboy advanced) Fire red and leaf green, for kanto (Nintendo DS) Heart Gold and Soul Silver. For Johto Heart Gold and Soul Silver. For Hoenn go the gameboy advanced route, Emerald, and for Sinnoh Platinum and diamond/pearl

For some people it is not based on the game play, but on nostalgia for the game they grew up with.
