>Sometime between 1985 and 1987, the game was advertised in Famitsu magazine as simply Excalibur. It was originally supposed to be an RPG trilogy for the Famicom Disk System and set in actual Medieval Europe.[6] Hiromichi Tanaka wanted the game to be something like a real-time version of Wizardry.[7]
>The game later remerged as Seiken Densetsu.[8] The first installment in the series, The Emergence of Excalibur, was only supposed to be the beginning of the story, which would consist in a five-game series that would unfold over several generations.[9]
