The development for Majora's Mask started out of a lack of enthusiasm to work on the unreleased expansion for Ocarina of Time for the Nintendo 64 Disc Drive, dubbed "Ura Zelda". Eiji Aonuma protested the expansion, so Shigeru Miyamoto challenged him to make a sequel for the game within 1 year, in exchange, they would no longer have to make Ura Zelda.
