Dragon Ball Z: Idainaru Dragon Ball Densetsu

Maybe it's heresy but I always preferred this game (Saturn version, of course) over its harder-to-find cousin, Dragon Ball Z: Shin Butoden. The air-based fighting, and the charge-and-momentum based fighting gameplay was addictive. It also matched the show's ne'er realistic approach to physical brutality - fighting taking place across both whole planets and episodes, and death being often reversible, subject to the whims of the story, not necessarily the action.
