Essentially the killer app for it's console and age, the jaw dropping spectacle fighter which sold the PS3's power to people. A game with amazing performances in terms of both blocking and voice work, Heavenly Sword needs preservation for people to understand why such a bizarrely designed console seemed a potential path to the future of consoles as a whole. It even displays the folly of mandatory motion control gimmicks, which is something only those of that time can truly believe otherwise. I'd love to have this available on GOG, to help people understand the time it was made and appreciate that great performances weren't some innovation of the 2000's or 2010's.
