I was reading up on some Ocarina of Time FAQS to try and enhance my 'gaming experience' and I came across this; 'The Uber Quest'
Basically what this is, is The Ocarina of time, However you Have to Follow some strict rules and Complete dungeons and temples in a different order than the storyline generally dictates. I haven't tried the Quest myself, as I am still playing my first time through the game and the task seems pretty daunting as I am not entirely familar with the game.
I do not know whether or not the actual challenge is possible (although the guide above says otherwise), however, If any of you do decide to take it on and succeed, then you've earned some serious bragging rights. The rules for the Challange are in the link above.
