Mecarobot Golf is a partial reskin of Birdie Try, a generic, non-robot-themed golf game starring Japanese professional golfer Nobuo Serizawa. Only the characters were changed, and the only sci-fi element in the US version is Eagle, the titular Mecarobot. Otherwise, the game remains a generic golf game, and the other three introduced characters are two white women and one white man, replacing the Japanese version's three Asian men.

In an interview with TechRaptor, lead developer Ryan Koons stated that the decision to make HuniePop a gameplay-centric title instead of a story-centric one like other dating sims didn't happen until months into development. The original intention was to make a traditional dating sim, only for Koons – who already had little interest in storytelling in video games – to overhaul the concept due to his growing ennui.

In the same interview, Koons stated that he deliberately sought to avoid many of the cliches associated with dating sims, particularly "the usual innocent waifu style character types." Consequently, the game's cast are based on people from his own life, and the writing is much more irreverent than other dating sims. In particular, Koons described deuteragonist Kyu Sugardust as a raunchy fictionalization of her voice actress, Jaclyn Aimee.

If the player shakes the game camera while over a snow tile, it will cause the snow to swirl around much like when a snow globe is shaken.

Performing El Blaze's item win pose with the maracas will feature Amigo from Samba de Amigo popping out of the maracas.

One of Kage's item win poses features him throwing a pan into the air and it landing on his head. This is a reference to a secret win pose he had in Virtua Fighter 3tb.

In Virtua Fighter 3tb, Jacky and Kage both have a secret win pose when holding Down, Guard, Punch, and Evade. They will perform "V for Victory" poses. If Kage is in his 2P costume and gets an "Excellent" victory on Akira's stage, he will perform a secret win pose where a metal pan will fall on his head.

In 2013, Square Enix published a novella titled "Final Fantasy X-2.5 ~Eien no Daishō~" ("Price of Eternity"), made to commemorate the release of the Final Fantasy X/X-2 HD remasters that year. It was written by both games' scenario writer Kazushige Nojima. The novella never received an official English release, and the only existing fan translation as of 2024 was translated from Japanese to French to English. The book was heavily criticized worldwide upon release for its contents, vague writing style, introducing violent and sexual elements uncommon to the Final Fantasy series at the time, and weakening the impact of both games' endings. For context, X's plot builds up to Spoiler:a negative ending where Tidus dies and Yuna has to accept his death and move on in life, while X-2 renders this moot, turning it back around to Spoiler:a positive ending centering on the possibility that Tidus is still alive and bringing him back to life at the end of the game. What X-2.5 does to weaken this is Spoiler:immediately kill Tidus and immediately resurrect him for the express purpose of setting up future stories, removing the emotional weight and finality of him being truly dead or alive.

X-2.5's plot takes place between the first ending of X-2 and its secret ending. It has two sections written from Tidus and Yuna's own perspectives before shifting to a section with both of their perspectives. After reuniting, Yuna is briefly separated again to address recent developments on Besaid Island. Tidus later goes sailing to look for her, falls asleep, and wakes up finding her in the boat. Spoiler:On their way back to Besaid, they get lost in a storm and are marooned on an island resembling Besaid, having transported 1000 years back in time. While there, Tidus inexplicably gets hit in the head with an object resembling a Blitzball that is actually a bomb. When he goes to pick it up, it suddenly explodes, decapitating Tidus and sending his head flying near Yuna with a surprised expression on his face. Yuna faints and sees a vision of a god-like figure who helps her resurrect a ghost-like version of Tidus through Beckoning, where someone thinks of a person they knew who died, summoning an illusion of them made of Pyreflies from the Farplane, but if that illusion learns they are not actually alive, they will fade away.

The rest of the story involves Yuna Spoiler:going back and forth from the past to present trying to keep Tidus' spirit from vanishing by interacting with several new characters, Briar and Kush, who also turn out to be Beckoned spirits from the past and vanish at the end of the book, and Ifarnal, a summoner who tells Yuna that Tidus must kill Kush if they want to return to the present together and later gets killed by another bomb. Through the subplot with these new characters, the novella establishes that one way to create "cores" used to summon Aeons (of which the Aeon Cores are established to be very similar to Faytes but also have several differences) is implied to be through consensual sex (in a scene where Yuna is transferred the knowledge on how to create them and blushes in embarrassment). At the end of the book, there is a small time-skip that occurs that shows Tidus and Yuna during the secret ending of X-2, showing it in a different context now knowing the events of the book, and ends on the implication of further continuations to the story.

This story would later be continued with Final Fantasy X-2: Last Mission, which came out years before X-2.5 and does not acknowledge the events of it, but the HD remaster does include a continuation to both that is relevant to the events of X-2.5. It is a 30-minute audio drama that was dubbed internationally called "Final Fantasy X -Will-" and was also written by Nojima. The story follows two summoners, Chuami, claiming to be the daughter of Auron, and her assistant Kurgum, who gradually meet the cast of the game as new events occur. Yuna discovers Spoiler:that several souls are being beckoned back from the Farplane, including Sin. In what seems to be an effort to prevent the still-ghostly Tidus from sacrificing himself to kill Sin again, she breaks up with him by lying about being in love with another man, and the summoners go off to fight Sin, appearing to set up the plot for a potential Final Fantasy X-III.

In the "3rd Mix PLUS!" variant of this game, there is unused data for the song "TOTAL RECALL" by ULTIMATE HEIGHTS. This includes unused graphics, step charts and lyrics for the song.

The Art of Fighting ending, which was a continuation from the ending from The King of Fighters XIV, features Khushnood from Garou: Mark of the Wolves. However, his name changed to Marco in this ending, which was his original name in the Japanese version of Garou: Mark of the Wolves. This was likely due to The King of Fighters XIV's director, Yasuyuki Oda, and art director, Nobuyuki Kuroki, asking on a livestream with SNK community manager KrispyKaiser if the fans would like his original name in future games. The chat overwhelmingly preferred the name Marco.

The Ziggy enemies appear to be modeled after Ziggy Stardust, a stage persona created and portrayed by English rock musician David Bowie from 1972 to 1973. In addition to the identical names, the Garden Ziggy variety features brightly colored lightning bolts painted across each eye and a large yellow mohawk, with the results resembling the cover photo for Bowie's 1973 album Aladdin Sane (which depicts Bowie with a red lightning bolt on one eye and a large red mullet).

In PAL releases of the PlayStation 2 version, the player is normally only able to access the tutorial in English, French, Italian, Castilian, and Dutch. Despite this, versions in the other supported languages (German, Swedish, Finnish, Danish, Norwegian, and Portuguese) are present in the game's data and can be accessed either through hacking the game or selecting a supported language and switching to an unsupported one with debug features just before the screen fades to black. It is unknown why these six variants of the tutorial were made inaccessible in the final game, given that they are fully translated.

Temjin, from Art of Fighting 2, and Mars People, from Metal Slug 2, make a cameo appearance in the "Friendly Fight" ending.

During an interview with Variety Fair, Todd Howard revealed that the 2024 live-action "Fallout" TV series was considered canon to the games, having wanted to tell an original story within the game's world rather than adapt any of the previous games. However, when the show came out, this lead to complaints from fans accusing the show of retconning the events of Fallout: New Vegas. Specifically, the sixth episode "The Trap" featured a shot of a blackboard seemingly depicting the fall of Shady Sands (the capital of the New California Republic) as taking place in the year 2277. Fallout: New Vegas takes place in the year 2281, yet Shady Sands is stated to still exist in the game without any mention of a fall (although the city cannot be visited in-game). Emil Pagliarulo, a design director for Bethesda, would try to assure fans on Twitter that Fallout: New Vegas is still considered canon, claiming to being overprotective of the series' lore and going as far as to post a timeline of the Fallout series. While the timeline not only featured both Fallout: New Vegas, the TV series, and also confirmed that Fallout Tactics: Brotherhood of Steel is considered canon to the series, it did not address the timeline inconsistency brought about by the blackboard scene in the show. This reportedly lead some fans to accuse Bethesda of holding a grudge against Obsidian Entertainment for making what many fans consider to be the best Fallout game and using the show as a way to spite them. However, it's worth noting that there are three other possible explanations for the inconsistency:

• Whoever wrote "2277" was misinformed due to the post-apocalyptic setting forcing many to rely on guesswork for event dates.
• It could be a simple mistake in writing for a series with large amounts of lore to it.
• It could be a reference to the "Lonesome Road" DLC expansion for New Vegas, where the player is given the option to nuke the NCR, though there is no confirmation that this ending is canon.

Ash's intro sequences with Kyo and Jivatma is a reference to Orochi Chris' win poses from The King of Fighters 2002.

According to lead level designer Enrique Colinet, Larian Studios was one of the largest backers during the game's 2017 Kickstarter campaign, donating an unspecified four figure sum and never asking for any backer rewards.

During the final battle in the Japanese version, Spoiler:a voiceover from Zelda states that the monstrous form that Calamity Ganon assumes is due to his obsession with maintaining his longevity. However, in the English localization, Spoiler:Zelda claims that this form is the result of him abandoning his ambitions for reincarnation and giving into his primal rage, which directly contrasts the Japanese script.

This also opens up a plot hole with Spoiler:Zelda's dialogue in the game's ending, where she says that "Ganon is gone for now" (emphasis added), implying that he will reincarnate anyway (as is the case in other entries, including the game's sequel, The Legend of Zelda: Tears of the Kingdom); in the Japanese version, she simply says that "the threat of calamity has passed."

Spanish for Everyone!'s plotline has been noted for containing stereotypical characters and seeming to have innuendo alluding to drug smuggling across the Mexican border. According to a developer, this was intentional as a way to have fun making a budget title, and inspired by the double meanings in the Shrek movies.

The South Korean version of the game (released two years after the original Japanese edition) contains eleven unused maps not found in any other release, featuring fully 3D environments which do not line up with any locations present in the finished product. All assets related to these maps are dated after the game's Japanese release, with intervals ranging from five days to just over three months. Additionally, the maps' texture names are written in Romanized Japanese rather than Korean, indicating that they were not created by Nintendo of Korea.

Two of these maps, kri_04 and kri_05, additionally feature various cat NPCs, all drawn in substantially different art styles compared to not only each other, but also the final game. Each one is named after a developer from the Super Paper Mario staff: yamada_neko02 (Koichiro Yamada), koba_neko (Sayuri Kobayashi), tuka_neko (Naoko Tsukamoto), and kawa_neko (Chie Kawabe).

Of these four, kawa_neko is the most unique, and was apparently designed as a player character. Firstly, the cat's name is only given to its mesh, with its sprite instead being named bc_all.1. Additionally, kawa_neko features an animated tail and a mesh that is centered on the ground rather than the middle of the room. Furthermore, new_neko_18, a redesigned version of kawa_neko with white fur instead of black, can be found in kri_08, kri_09, and kri_10; new_neko_18's mesh is explicitly labeled "PLAYER" in the data for these maps.

Taken together, all of these elements imply that these early rooms were created as a proof-of-concept for an original project by Intelligent Systems that ended up cancelled for unknown reasons.

According to a tweet by dj TAKA, the song "ABSOLUTE" was originally called "Special Thanks". The name was changed after CG Designer VJ GYO and illustrator GOLI thought the name was "lame".

Baldur's Gate 3 was the first AAA game to win all five of what is referred to as the major Game of the Year awards, those being the BAFTAs, The Game Awards, DICE, Game Developers Choice, and the Golden Joystick awards.
