From its inception, one of the defining features of The Legend of Zelda series of games was the two-dimensional top-down perspective; from The Legend of Zelda, to A Link to the Past and Link's Awakening, a broad trend for the series began to emerge. But this was all to change with the 1998 release of Ocarina of Time, the first game in the series to employ full 3D graphics. To date, almost all games in the series have adhered either to the newer 3D format, or to the more traditional 2D format. The only exception to this is The Adventure of Link which uses a combination of a 2D overworld and side-scrolling battle formats.
