Licensing
In the original arcade game, the red, blue and yellow CPU trucks were 'driven' by "Madman" Sam Powell, "Hurricane" Earl Stratton and "Jammin'" John Morgan, respectively. The names were taken from the development staff: Sam composed the music, and Earl and John were two of the software programmers. The Track Pack added "Steamin'" Steve High, and "Hot Rod" John Rowe, representing graphics and project direction, respectively. By using these names, this meant that further licensing deals were not required.
The Super NES version was notable for prominently featuring the Toyota brand; the name and logo were displayed on various tracks, and pre-race music was inspired by the "I love what you do for me Toyota" jingle that was used by the company's marketing campaign at the time of the game's release. This version also lacked any licensing or reference to Ivan Stewart, replacing him instead with the late Mickey Thompson in the gray truck. The NES version does have the Toyota label on its cartridge art, but otherwise the ad is not present.
The game was not originally developed or published by Williams, Midway, or Atari Games but by the Leland Corporation (which was acquired by WMS Industries, the holding company of said developers, in 1994). Both the Arcade version of the game and its "Track Pack" upgrade can be found in Midway Arcade Treasures 3. However, it does not have the "Ironman" Ivan Stewart license, and as such is known simply as "Super Off Road", with the white, computer controlled car being "driven" by "'Lightning' Kevin Lydy" (in the original arcade cabinet, the white car is "driven" by Ivan Stewart). While Kevin Lydy is a real person, he is not an off road racer. He is, in fact, one of the graphics staff on the original arcade game, continuing the previous tradition regarding the CPU drivers.
