Ocarina of Time earned the title of Greatest Game from being in the right place at the right time. It was a large, free-roaming 3D adventure game, the first one to strike with a powerful brand behind it (The Legend of Zelda, and Nintendo). 3D was still new, and this one wowed everyone.
Super Mario Galaxy may take third, it'll come really close to Super Mario 64, but I don't think this industry will ever see another Ocarina of Time.
