JoJo's Bizarre Adventure: Heritage for the Future was originally released as JoJo's Venture in December 1998. This version suffered from a rushed development, reflected by the abundance of unused assets in its code, including both finished and unfinished sprites for various attacks, cutscenes, and HUD elements. An updated version would come out eight months later, this time using the series' full title and adding the Heritage for the Future subtitle. A significant chunk of the unused assets in JoJo's Venture would be polished up and incorporated in this newer version.
