Micro Machines, released in 1991 on the NES and in 1993 on other formats, was the first game in the series and laid the foundation of the gameplay: a top-down racing game with miniature vehicles. The race tracks are unconventionally themed. For example, some races take place on a billiard table while others occur in a garden. The cartridge itself was gold (black in Europe) with a switch at the bottom in order to be compatible with the American and European hardware. It was also released as an add-on to the Aladdin Deck Enhancer created by Codemasters.
