Ultima influenced ゼルダの伝説 (The Legend Of Zelda)

The Zelda team has credited the American computer RPGs, Ultima among them, for the shape of the overworld: a continuous top-down land explored freely, with dungeons set into it and equipment that changes where you can reach. Miyamoto's own stated starting point was different and personal, a childhood memory of finding a cave, and Zelda drops the things that make Ultima an RPG. There are no experience points, no classes, no party and no statistics. Filed MEDIUM for exactly that reason: the debt is to the exploration structure rather than to the rules.
