NES Open Tournament Golf

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.

A version of this game was developed for the Nintendo PlayChoice-10 in the Americas, called Mario's Open Golf.

NES Open Tournament Golf has also been released on the Virtual Console for the Wii for 500 Wii Points, as well as for the Nintendo 3DS's Virtual Console in 2011 and the Wii U's Virtual Console in 2014. The original Famicom game is also one of the 30 titles included in the Japan-exclusive Nintendo Classic Mini: Family Computer. The game was also made available for Nintendo Switch Online members on October 10, 2018. In Family Computer - Nintendo Switch Online, apart from the standard version, a special version titled "マリオオープンゴルフ フルオープンバージョン" (Mario Open Golf: Full Open Version), where all courses are unlocked, was also released on November 14, 2018.

Differences in the Japanese version

 * Due to the lack of the tournament mode, the plot is different. Instead of trying to win $1,000,000, Mario must instead finish all five courses in Stroke Play mode.
 * A scoring limit is introduced for stroke play; if the player goes over the scoring limit, they must restart the course from the beginning.
 * Donkey Kong, Mark, and Steve are absent from the Japanese version.
 * The title music is different, and both the Options menu and cutscene themes play at different pitches within the same octave.
 * "Hall of Fame Holes" are called "Memorial Holes".
 * Not only are there more courses, shared holes are often more difficult in the Japanese version due to more obstacles and traps, although some are made less so due to the removal of certain hazards on them. For example, the Japanese hole 5 of the Japan course has an extra strip of fairway attached to the upper-left corner of the green, while in the NES version, said strip is replaced with a water hazard.
 * The ranks (Semi Pro, Beginner, etc.) are unlocked after completing certain courses past the second one. The default rank is none at all.
 * Not all courses are available at the beginning; instead, the courses after the first one (Japan) must be unlocked by beating the previous one. The extra course is a compilation of all holes the player has unlocked, and there is no reward for completing it. In the Full Open Version, all courses are unlocked from the start.

Tournament Roster
In the Club House mode in the game, there is a setting called the Tournament Roster. Here the player can change all of the player's names, just like they'd change their own name (which is Mario by default). Here are all the 36 default names on the Tournament Roster. The player cannot change the roster in the Japanese version due to a lack of a tournament mode.

All of the names starting from Miki to Uemura are names of the people who developed and produced the game, while Steve and Tony are names of two people who localized it for North America.

Staff
NES Open Tournament Golf was a coproduction between Nintendo R&D2 and HAL Laboratory. Kenji Miki (director of the original Golf) was the director. The game was Satoru Iwata's first experience in developing a game "from start to finish". The title was also Eiji Aonuma's (credited as a sprite designer) very first work in the video game industry.

Trivia

 * Dummied data for the game Animal Forest + indicated that Super Mario Bros.: The Lost Levels (or, more accurately, Super Mario Bros. 2) as well as NES Open Tournament Golf would have been included as a playable Famicom game, but it ultimately was cut, with not even a ROM or models available inside.
