14The Legend of Zelda: A Link Between Worlds
After Spirit Tracks released on the Nintendo DS, a small team in Nintendo began work for a Nintendo 3DS game. Their original concepts differed greatly from A Link Between Worlds, but their ideas were not approved. The team continued brainstorming and thought of the brilliant mechanic used in A Link
Between Worlds where Link walks inside walls. The concept was wonderfully executed, creating dynamic gameplay in which you explore dungeons’ floors in a top-down perspective and their walls in a side-scrolling perspective.
Soon after work had begun on this mechanic, Nintendo shifted their focus from the 3DS to the upcoming Wii U. The 3DS wall-traveling mechanic was abandoned, but fortunately revisited a year later, allowing A Link Between Worlds to fully develop.
