Tetris may have been the milk the Game Boy was nursed with, but Pokemon was the meat that fed its appetite for half a decade. And as nostalgic as I am to earlier games, it is hard to deny that the second generation is the definitive RPG title of handheld gaming history, with Crystal being the most complete version. Game Freak is sometimes criticized for not moving beyond these roots quickly enough, but growing beyond something like Pokemon Crystal is something few can accomplish.
