The Legend of Zelda
The Legend of Zelda was the very first Zelda game released. It centers its plot around a boy named Link, which becomes the central protagonist throughout the series. It came out as early as 1986 for the Famicom in Japan, and was later released in the western world, including Europe and the US in 1987. It has since then been re-released several times, for the GameCube as well as the GameBoy Advance. The Japanese version of the game on Famicom was known as Hyrule Fantasy, abbreviated as HF. Some use this title to keep people from getting confused with the other games in the series. Also the NES cartridge for The Legend of Zelda was formatted in 1987, with a internal battery to facilitate game saves.
