"You know I wonder why Nihon Falcom despite having made remakes of some of their past entries of Ys have yet to rerelease or remake one that has only ever had a JP release.

Their Ys titles they have done the remakes to are Ys Oath in Felghana is a remake of Ys III: Wanders of Ys, while Ys: Memories of Celceta is simultaneously a remake and Nihon Falcom's own version and canonical Ys: IV. Since they had originally outsourced Ys IV's development to two different companies which resulted in two versions of Ys IV, Ys IV: Mask of the Sun (Super Famicom) by Tokin House and Ys IV: Dawn of Ys(PC Engine/TurboGrafx-16) by Hudson Soft. Both games tell essentially the same story as its more than likely Nihon Falcom provided the story for Tonkin House and Hudson Soft to use when they were tasked with making Ys: IV.

But as of yet they have yet to do any sort of release or remake of Ys V: Lost Kefin, Kingdom of Sand, this one to this day still remains a JP only release title way back for the Super Famicom. I wonder why they haven't revisited this one. All other Ys titles that I am aware of have been released outside of JP, save that one."
