Seifuku Densetsu Pretty Fighter X, by Imagineer, is a Japan-only fighting game featuring uniformed schoolgirls, the Saturn sequel to a series begun on Super Famicom. Its notable technical quirk is the mandatory 1 MB RAM expansion cartridge, an accessory that narrowed its audience and print run. The steep climb in value toward sealed condition reflects the scarcity of intact copies of a niche title rarely reissued, sought by fans of obscure Japanese versus games.
