This game marks Falcom's first multi-platform release. Prior to Nordics's release, they typically develop primarily for PlayStation consoles with ports to other consoles being done by them or other companies later down the line.
Limited Special Collector's Ultimate Edition: The game's Japanese collector's edition (named the Adol Christin Edition) includes a body bag, several art cards, a mini soundtrack cd, a logo pin and a DLC code of Adol's iconic silver armor costume.
Pre-Order Bonus: Pre-orders of the game includes two pikkard related costumes (one a ridable pikkard plush that is attached to the character's back and another is a full pikkard costume).
Word of God: Toshihiro Kondo has stated that Adol and Karja's relationship is intended to be platonic and more Like Brother and Sister. This is in contrast to the other female deuteragonists, who all develop feelings for Adol.
