The Legend of Zelda: Ocarina of Time
The most notable feature of Master Quest is that every dungeon in the game has been modified to increase the difficulty of the game. Each one features a different layout, changing the progression through the levels. Enemies are spread differently throughout the dungeons, and tougher enemies are encountered much earlier on than in Ocarina of Time. In addition, some Gold Skulltula locations in dungeons have been moved, and certain items that are optional in the original version are now mandatory to complete the game.
