The Legend of Zelda: Ocarina of Time Master Quest

Master Quest was originally an expansion to Ocarina of Time planned for Nintendo's ill-fated Nintendo 64 addon, the Nintendo 64 Disk Drive system. When the 64DD failed in Japan, Nintendo cancelled the release of the Master Quest. As time went on, the nearly complete game sat wasted and unplayed. Nintendo decided to change this when they announced that they had ported Ocarina of Time to the Gamecube and would include Master Quest along with it in a special preorder campaign for Zelda: The Wind Waker.

The Master Quest alters the original dungeons present in Ocarina of Time and makes them much more difficult to complete. Aside from this, much of the game, including the overworld, remains unchanged. The only way to obtain this game so far is the special preorder disk for the Gamecube. Although the discs are clearly labeled as "not for resale", game retailers still regularly buy and sell used copies of the game.
