This second version of the story of Ys IV was released on December 22nd, 1993 in Japan as a CD title for the PC Engine (TurboGrafx-16), roughly a month after Mask of the Sun’s release. Despite taking place in the same general setting as Mask of the Sun, Dawn of Ys features a significantly altered storyline and is a fairly radical departure from Falcom’s original plot outline. Despite this, it is generally the most highly regarded version of Ys IV by fans of the series.
