Don't mistake "Super" Off-Road for some halfhearted sequel, oh no!
This is the original, spin the steering-wheel like a sea-captain, skip the shocks, buy the acceleration, rumble around yet another brown dirt track via a locked overhead pespective stand-up arcade racing classic you know and love so well.
There is no functional difference between the arcade version and the Super NES Version, except the lack of a big, freely rotating wheel to steer by.
