Company: Nintendo

Revealed in concept art by former Retro Studios employee Sammy Hall, Retro Studios actually worked on two major projects for Nintendo using two of their biggest IPs before Nintendo cancelled them for unknown reasons.

One of them was a project in the Mario series centered around the supporting character Boo. Little is known about the project outside of the Concept art, but hints released with the concept art tease that it would have been released for one of Nintendo's handhelds (such as the DS) as well as there being things in the game referred to as "possession powers" and "Broomies".

The other game, rumored to be centered around the character of Sheik from The Legend of Zelda series, was more elaborate. Hints leaked by Hall and released with the concept art suggest that it would of been about, and centered around, the origin of the Master Sword in the Bad Timeline and would feature "the last Sheik" as it's main character. The game would have also seen the Dark Gerudo tribe engaging in their decade-long birth to Ganon. The project was describe as an "Action/RPG".

According to Shigeru Miyamoto in a Keynote speech at the 2018 Computer Entertainment Developers Conference, the reason he and Nintendo never created an MMORPG game (and probably never will) is because he personally finds it boring and tiring to have to handle a game that needs constant updates and attention for an extremely large amount of time and would thus rather create a great number of unique games constantly over the same timespan.

Nintendo's First Gaming Console was a Pong Console "Color TV-Game 6". It was only released in Japan in 1977. Nintendo made a update a few years later "Color TV-Game 15" with 15 Games and detachable controllers.

Nintendo prohibits Shigeru Miyamoto from either walking or biking to work, asking him to drive instead. This is because he's become an invaluable asset to the company and they fear he might get hit by a motorist if he commutes to work outside the safety of a vehicle.

Nintendo once attempted to buy the exclusive production rights to the Harry Potter franchise. J.K. Rowling turned it down in favor of several other proposals by media giants with greater resources, such as Disney and Universal. Whereas Nintendo was only able to offer video game adaptations of the books, these larger companies had the ability to adapt the franchise for television and film, as well as gaming.

In the end, Rowling sold the rights to Warner Bros., who would later contract Electronic Arts to create the video game adaptations of the Harry Potter film series.

At E3 2015, Nintendo's press conference featured puppet versions of Satoru Iwata, Shigeru Miyamoto, and Reggie Fils-Aime between announcements; these puppets were created by the Jim Henson Company, the same studio known for producing The Muppets and Sesame Street as well as the original Yoda puppet in Star Wars.

Nintendo had filed a patent for a mobile gaming phone, though the concept was never used. The patent was filed on November 27, 2001, however it wasn't published until June 27, 2006.

Nintendo's original headquarters are located in the territory of the Aizukotetsukai, one of Japan's oldest and most powerful Yakuza groups, and their hanafuda cards were primarily used in Yakuza-owned gambling dens.

In 1988, the Ralston Cereal Company released a Nintendo based cereal called "Nintendo Cereal System." It had two different types of cereal in it, one based on Super Mario Bros, tasting fruity, and one based on the original Legend of Zelda, tasting like berry. It was discontinued a year later.

On average, Nintendo has released a new console every 5-6 years.

Nintendo started out as a card company under the name Nintendo Koppai. They made Hanafuda cards when they started becoming popular. This lasted from 1889-1928. Nintendo continues to manufacture cards with Nintendo themes on the Nintendo web site in Japan.

Nintendo used to be the majority owner of the Major League Baseball team "the Seattle Mariners" since 1992, but sold most of their shares in the team in August 2016, currently retaining 10% ownership.

Shigeru Miyamoto had little interest in videogames until the late 1970s, when he played Space Invaders. Up until that point, he had wanted to be a manga artist.

Nintendo released one console to a Chinese-only market. It is called the iQue and is based on the Nintendo 64, though there is no physical console as it is completely contained in the controller. A total of 14 games exist for it which are downloaded from the iQue Games Depot directly to a 64 MB flash card which is connected to the controller via a cartridge.

Each Nintendo console was developed under a code name, and Nintendo hides the consoles' code name as a 3-4 letter abbreviation on the game or console's box or cartridge. For Example, somewhere above the bar-code on Pikmin is the label "DOL P GPVP" DOL stands for Dolphin, the GameCube's Code name.

The code names and abbreviations are:
(NES) for the Nintendo Entertainment System (acronym).
(SNES) for the Super Nintendo Entertainment System (acronym).
(DMG) Dot Matrix Game, code name of the Game Boy.
(NUS) Nintendo Ultra 64 (sixty-four), code name of the Nintendo 64.
(CGB) For the Game Boy Color, assumed to mean Color Game Boy.
(AGB) Atlantis, code name of the Game Boy Advance (Atlantis/Advance Game Boy).
(DOL) Dolphin, code name of the Nintendo GameCube.
(NTR) Nitro, code name of the Nintendo DS.
(RVL) Revolution, code name of the Nintendo Wii.
(CTR) For the 3DS, the Codename of the 3DS is still unknown.
(WUP) For the Wii U which may simply stand for 'Wii U Project', though its code name was Cafe.

Kazumi Totaka, a sound designer for Nintendo, is known for inserting his song, Totaka's Song, into many of the games he has worked on.

In the 1960's, Nintendo opened a "Love Hotel", which is a type of short stay hotel operated primarily for the purpose of allowing couples privacy for sexual activities.

HAL Laboratory, Inc. (a second-party developer known for creating Nintendo's Kirby and Super Smash Bros. series) named themselves "HAL" because each letter in "HAL" is one place ahead of each letter in "IBM", as if to say HAL were one step ahead of their competition.

In 2020, hackers Gary Bowser and Max "MAXiMiLiEN" Louarn were arrested and extradited to the United States for money laundering and selling products meant to crack the Nintendo Switch's copy protection to run pirated copies of games. The two were members of Team Xecuter, a hacking group which specialized in similar measures for a large number of Nintendo, Sony, and Microsoft consoles. In 2021, Bowser pled guilty on conspiracy and trafficking charges and was sentenced to 40 months in prison; Nintendo later filed a separate civil suit against him, which together with the prison sentence left him $14.5 million in debt. The company's legal department claimed during the court case that the unusually severe punishments were intended to send a chilling effect through the piracy world, intimidating would-be hackers by using Bowser's punishment as an example.

Following the case, multiple news outlets noted the irony of Gary Bowser's last name, which is shared with Nintendo of America president Doug Bowser and Mario series antagonist Bowser.
