NES Open Tournament Golf (known as Mario Open Golf in Japan) is a NES game featuring Mario characters. As the name of the game implies, it is a golf game and was one of the first golfing games in the Mario series. In the American version of the game, the graphics and soundtrack have slightly changed. The Japanese version of the game features different playable courses and fewer characters. Although the Japan and UK courses are also playable courses in the American version, they do not contain the same holes. For example, hole 5 in the Australia Course is hole 15 in the US Course. The game does not take place in the Mushroom Kingdom and instead takes place on Earth, or the "real world." The levels are Japan, Australia, France, the United Kingdom, and the United States of America.
