The Legend of Zelda: Ocarina of Time 3D is a 2011 action-adventure remaster of the iconic 1998 Nintendo 64 game, co-developed by Grezzo and published by Nintendo for the 3DS. It revitalizes the classic with stereoscopic 3D, touchscreen inventory controls, gyroscopic aiming, and adds the challenging Master Quest dungeons plus a new "Boss Challenge" mode. The plot follows hero Link as he travels through time to stop Ganondorf from seizing the Triforce, using an ocarina to play magical songs. Shigeru Miyamoto intentionally timed the release so the original players would be in their mid-20s, and the developers even preserved some of the original's quirky bugs to maintain nostalgic charm. The game was a critical and commercial triumph, selling over 6.44 million units to become the 13th best-selling 3DS title, and it paved the way for a sequel remaster, Majora's Mask 3D, in 2015.
