The success of "Kunio-kun" led to the production of numerous spin-offs and sequels starring the same character produced for the 8-bit Family Computer platform in Japan and later for the Game Boy and Super Famicom, resulting in more than twenty games starring Kunio by the mid-1990s, many of which were rule-bending sports games. A few "Kunio-kun" games were localized for the North American market; namely "Super Dodge Ball", "River City Ransom" (considered by critics to be a cult classic) and "Nintendo World Cup", but none maintain any connection with each other. Technōs would attempt to remedy this by attempting to localize several "Kunio-kun" under the "Crash 'n the Boys" label, but only "" was released (the game's ending features a teaser for "Ice Challenge", which was unreleased).
