Huh, and here I had been assuming that Kinniku Banzuke = Ninja Warrior. I never knew Ninja Warrior was just a spin-off. It probably doesn't help that I do have a copy of Kinniku Banzuke: Road to Sasuke but none of the other Kinniku Banzuke games. And I somehow missed Unbeatable Banzuke back in the day but did watch Ninja Warrior, which I really liked (but American Ninja Warrior doesn't appeal me to at all).
