4x4 Off-Road Racing
4x4 Off-Road Racing is a single-player truck racing game published by Epyx in 1988. The game gives you a budget and allows you to choose your own 4x4 truck, customize it, and purchase tools and parts for repairs. With your outfitted 4x4, you race along one of the game's four tracks and comically careen off the dangerously littered roads.
4x4 Off-Road Racing was originally released on the Commodore 64, and was ported to numerous platforms. The DOS port appears to miscalculate miles per gallon making it impossible to carry enough gas to finish a race.
