According to the game's Japanese website, K. Lumsy is King K. Rool's younger brother. This detail is not mentioned at any point in the English version of the game.
In an interview conducted to promote the 2025 remaster of Off, Toby Fox cited the original 2008 PC release as an influence on Sans and Papyrus in Undertale. Sans was inspired by both Zacharie and the Judge, specifically noting the former's comic relief status, constant smiling, and ambiguous motives. Meanwhile, Papyrus' design was originally based on Dedan, as indicated by early concept art which Fox posted on Twitter. Additionally, Fox cited Off's jazz-driven soundtrack as an influence on the song "Ghost Fight" (and, by extension, "Dummy!" and "Mad Mew Mew").
The 2025 remaster of Off replaces the soundtrack from the original 2008 PC release with a new score due to the composer, Alias Conrad Coldwood, being reluctant to sign away the rights to his music. According to Toby Fox, one of the guest composers for the new score, Coldwood held no ill will towards the decision to replace his work, giving his approval towards the 2025 version's soundtrack.
Fox also stated that he was hesitant to contribute to the new soundtrack, comparing it to "breaking into somebody's house and pasting your face into their family photo album." Ultimately, he agreed to come on board after being directly asked by the game's creator Mortis Ghost. Fox stated that his most difficult contribution was the main battle theme, likening the assignment to "[taking] a bullet in the back for everybody else." He started by listening to several jazz recordings from the 1920's, and then commissioned frequent collaborator Carlos Eiene to record a "fake jazz song" in that style for him, which Fox then chopped and screwed into six different permutations. The first of these was then remixed several more times by frequent collaborator Masaya "Camellia" Oya, with each mix being intended for a different portion of the game.
In North America, Harvest Moon 64 is rated E for Everyone by the Entertainment Software Ratings Board despite the game's content warning stating that it contains "Use of Alcohol and Tobacco". While Nintendo of America was known for its strict censorship policies in the 1990's, all known instances of alcohol and tobacco use in the game were left intact for the North American release. The presence of tobacco in the game is very minor, with one known instance being in the overworld sprites of the Head Carpenter as he can sometimes be seen smoking a long pipe. On the other hand, wine, liquor, beer, and the social bonding aspects of drinking culture have a larger presence in the gameplay and the world-building of Flowerbud Village, including a side quest to restore the Moon Mountain Vineyard.
While farm animals can die from starvation, disease, or old age in the Harvest Moon series, they cannot be physically beaten, harmed, or killed by the player. This is a specific design choice in line with a recurring concept across Natsume's games referred to as "harmony with nature", or living in harmony with and respecting plants and animals. In a 1999 interview with IGN, Natsume president Yasuhiro Maekawa explained that this concept was used not because they wanted to make games with Shintoist beliefs, but because they wanted to focus on niche markets by doing something different from popular "bloody fighting titles" instead of competing with them.
Based on an early version of the script, Snide was originally going to have a slightly different backstory and motivation for helping the Kongs. Rather than being King K. Rool's chief technician like in the final game, Snide was instead his personal handyman who grew frustrated that K. Rool wasn't letting him work on bigger projects such as the "Super Gun" (the original name for the Blast-o-Matic), eventually deciding to betray him. Notably, instead of mentioning time (in reference to the final level being on a time limit), Snide instead mentions the weapon having "weak points". It's unknown if this is based on an earlier version of Hideout Helm, or if it's just another way of describing the energy barriers, which are called weak points on the complete blueprint.
The game's character select screen notoriously features unflattering portraits of the playable soldiers, which sharply contrasts with the bravado that would otherwise be associated with its militaristic setting. In the years following the game's release, fans speculated that the portraits were intended as either covert anti-war messaging, or as in-universe propaganda disseminated by General Morden's forces.
These theories were eventually debunked in a tweet by lead artist Akio Oyabu in 2025, who explained that the portraits were designed to lend a sense of comedic novelty to the game, humorously standing out from the "handsome men and beautiful women" that were omnipresent in fighting games at the concurrent height of the latter genre's popularity. Oyabu stated that he was influenced by Terry Gilliam's surrealist cutout animations in the 1969 British sketch comedy series Monty Python's Flying Circus.
The title screen and main menu of the Nordic release of the Nintendo DS port has a few notable differences from the European version. Specifically, the "Licensed by Nintendo" screen uses the company logo instead of just plain text, a logo for Mobiclip Video Codec present in the European version is removed entirely, and a language select screen with options for Swedish, Danish, and Nordic translations is included.
Beating the game with 100% completion unlocks a final cutscene which reveals that the monkey who gave you chants throughout the game is Spoiler:AiAi from the future. This cutscene further reveals that Spoiler:AiAi and GonGon invent the magic energy balls that the series' cast run around in, Baby is AiAi's future son, and that MeeMee is Baby's mother.
When the game was initially released in Japan, it was only available to people who bought a copy of the November 1996 cover-date issue of Japanese magazine CoroCoro Comic and filled out a mail-order form for the game. This promotion lasted from the day the issue was released on October 15 until December 27, 1996. As a result, on some official Japanese Nintendo and Pokémon websites, October 15, 1996 is listed as Pokémon Blue Version's first release date in Japan before it received a wider retail release there on October 10, 1999.
The title "Untitled Goose Game" was first used after submitting the game to Fantastic Arcade, a game festival in Austin, Texas, due to the team's indecisiveness with choosing a name. The game was internally referred to as "Goose Game" before then, although that was deemed unusable for the final release. However, the placeholder title they chose stuck due to positive public reactions, technically (and ironically) leaving the game without a title.
One Piece: Great Pirate Colosseum and Dragon Ball Z: Extreme Butoden, two games developed by Arc System Works for the 3DS, both received an update in November 2016 that added cross play where characters from one game can fight characters from the other game.
According to Cave Story creator Pixel around the release of Cave Story's Secret Santa in December 2021, the Mimiga named Santa did not get his name because it was related to Christmas or Santa Claus, but because he was the third Mimiga that Pixel designed during the original game's development. The name actually comes from "san" ("三"), the Japanese numeral kanji for three. At the same time however, Pixel acknowledged that some segments in the Bushlands where Quote has to travel through and collect items from fireplaces (including the one in Santa's house) may have subconsciously made him think about Santa Claus, though he did not realize this at the time. Santa would later take on a Santa Claus-like role in Cave Story's Secret Santa.
Darth Vader and Yoda from the Star Wars series appear as guest characters in the game, with Darth Vader being exclusive to the PlayStation 3 version, and Yoda being exclusive to the Xbox 360 version. According to Bandai Namco Entertainment America's then-senior business development director Zack Karlsson, this was a deliberate choice to match the color schemes of the respective consoles, with Darth Vader’s shiny black armor matching the PS3's look, and Yoda's green skin and white robe matching the 360's look.
In a 2004 interview with the magazine Nintendo Dream, designer Yoshio Sakamoto revealed that developing Wrecking Crew permanently increased the storage capacity of Famicom games. The cartridges previously had a maximum storage of 128 kilobytes (kb) of uncompressed data for programming and 64 kb of data for images and sprites in the game itself. Wrecking Crew's gameplay pushed developers towards a 256 kb capacity while still having 64 kb of image data, allowing for more complicated ideas to be explored. This increase would not be seen again until the Famicom Disk System allowed for 1 megabyte (1024 kilobytes) of storage per game.
In a 2006 interview with Dengeki Online, lead writer Kinoko Nasu and character designer Takashi Takeuchi noted that they were never fully satisfied with the original PC release of Fate Stay/Night, considering it only 95% complete. However, rather than their beliefs stemming from the inability to add content, the pair stated that their main issue was that they didn't remove enough, with Takauchi calling the PC version cluttered and overlong. Consequently, a major challenge during the development of the PlayStation 2 port, Fate/Stay Night: Réalta Nua, was striking an ideal balance between streamlining the game and adding in additional material to incentivize purchasing it over the PC version.
According to Lizardcube's art director and CEO Ben Fiquet, SNK approached them to make a game based on the Metal Slug series some months after the release of Wonder Boy: The Dragon's Trap. However, Mr. Fiquet turned down the offer, explaining that "the challenge artistically would be far too great, and I felt I could not do it justice".
According to a series of tweets on TeamKill Media's Twitter account, they announced the game would remain exclusive to PlayStation 5 and would not receive PC or Xbox Series X/S ports despite being requested by players. The reasons why were in regard to a lack of staff to handle porting it to Xbox consoles, and personal concerns over the chances of mods of vulgar or sexualized versions of the game's characters being added in the PC version. They stated that they held their voice cast in high regard alongside their artistic vision for the game and story, believing that mods would tarnish that standard and giving players the option to mod was "not worth the extra money we can make." This announcement led to complaints from some accusing TeamKill of both moral grandstanding and being paid by Sony to keep the game a PS5 exclusive, the latter of which they denied and insisted they received "no investment or support from anyone but ourselves." One of the most notable complaints came from Postal series developer Running With Scissors, who put out a statement defending modders and their role in buying games and keeping their fan communities alive with free add-ons.
In the English-language version of Super Mario 64 DS, a Toad holding a secret Power Star gives a hint that the mirror room contains an "ally with info", referring to how one can pick up an invisible Power Flower to access a Wario painting in the reflection of a Luigi painting. This hint has perplexed many players as to the identity of the "ally with info", with the leading theories being either that the Power Flower is the ally or Wario is the ally. The original Japanese-language text doesn't exactly give a concrete answer, with the Toad simply saying that he saw an invisible person inside the mirror, which is also a mysterious statement, but a contextually appropriate one as opposed to interfering with the hint. However, the European localizations show the real intent behind the English version through extra information not provided in English, that the ally will give a hint by not being reflected, meaning that the ally's identity is actually Luigi. The English version not only left out this crucial context, but also failed to disable the line after Wario is unlocked, something that was managed in other versions of the game.
Although the Wii port of the game was primarily developed with the Wii Remote and Nunchuk combo in mind, the game has limited Classic Controller support via the left and right analog stick.
