According to creative director Jason Mallett, the remake was originally built using assets from the original Epic Mickey, but was later rebuilt from scratch in Unreal Engine 4 using original assets. Reportedly, the developers used the fan-made Epic Mickey Wiki hosted on the wiki farm Fandom and YouTube videos as reference materials for the remake.

Mad Dash Racing was the first game released for the Xbox on November 6, 2001 in North America, nine days prior to the console's North American release on November 15, making it a "pre-launch title" of sorts.

Spanx from Whiplash was originally introduced two years earlier as a guest character in Mad Dash Racing, as both games were being developed at the same time by Crystal Dynamics. When Whiplash did release, Spanx sported a new design and was completely mute, though some traits from his appearance from Mad Dash Racing carried over, such as his jittery movements.

The Genron employee Roman Polański is a not-so-subtle reference to film director of the same name, even being dubbed as such by Redmond. Upon returning back to the Robotics section and defeating his upgraded form "Robo Polański", Redmond turns to Spanx and references a quote from Polański's 1974 film "Chinatown": "Forget it [Spanx], it's Chinatown."

The title screen of 7 Grand Dad uses a redrawn version of one of the Mario sprites from the 1989 Famicom bootleg game Dian Shi Ma Li.

As of 2026, The Legend of Zelda: Twilight Princess and its HD remaster are the first and only games in The Legend of Zelda series to receive a Teen rating from the Entertainment Software Rating Board.

Shortly after the release of the DLC pack THE JAMIE PAIGE CONTENT COMPANION, the in-game music video for "Machine Love" was quickly replaced with a censored version. This edit modifies a shot of three spinning Kasane Tetos to replace the caption "the fucking creature?" with "this time i'm really gonna do it" (referencing a meme originating from YouTuber Brutalmoose's 2013 review of Simtown), blurs a shot of two Hatsune Miku plushies being tossed into the air, and adds an animation of Jamie Paige exploding atop the latter. The edited caption is likely to maintain a T rating from the ESRB, while the censorship of the Hatsune Miku plushies is most likely due to rights issues regarding the character's likeness.

Kaori Mizuhashi, the voice of Navi in the original game, reprised her role in the Japanese version of the game's 2026 remake, making her the only actress from the original game's voice cast to return. According to the remake's director HokWai Ng and series producer Eiji Aonuma, they did not plan this and had unknowingly cast her again during blind auditions as they were attempting to find performances that "recreated the sound and feel of the original game."

Stahn's younger sister Lilith was originally planned to be a recruitable party member, but the intended route to recruit her was removed during debugging before release; Lilith would later appear as a hidden party member in the PlayStation 2 remake of the game. For almost 29 years, it was believed that the only way to recruit Lilith in the original PlayStation version was through a bug you could perform in Dycroft in the first Japanese release, but recruiting Lilith would trigger a softlock by preventing a necessary scene flag from playing out.

This would all change in November 2026, when the administrator of the long-running Tales of series fansite Majestic Phantasian reported that he found a complicated, but legitimate method to recruit Lilith in the original Japanese version without the use of glitches. He also reported that the softlock can be circumvented by saving before entering Neuestadt after recruiting her, turning off the game, and then loading a later revision of the Japanese version that was only released under the budget marketing label "PlayStation the Best". The softlock was fixed in this version of the game, allowing the save data to carry over and let you finish the game with Lilith in your party. While it was initially thought this was limited to the Japanese version due to it requiring two different Japan-only revisions, it was discovered by a group of English fans the following day that both this method and the softlock fix were included in the original English version of the game. The recruitment sequence was fully translated, but had visible line-wrapping text issues, indicating that it was not fully tested before release.

The game's co-producer Jun Toyoda congratulated the players and revealed that this method was unintended as the development team was supposed to completely omit Lilith as a party member. They were unable to do so due to time constraints that resulted in five major bugs, including the softlock, being left intact, which he apologized for.

In Chapter 3, if a battle against a Shadowguy lasts for at least four turns, the Shadowguy will have a 1% chance of having his attack replaced by a text box reading: "This bullet pattern has been censored by the MPA." In the Japanese version, the reference to the real-world Motion Picture Association is replaced with a mention of the "BBPO," likely a misspelling of BPO, the Broadcasting Ethics and Program Improvement Organization.

Within the game's data are walking and portrait sprites for Sans, a character from Undertale, associated with the Wild East area. According to programmer Spasco, these are remnants of a cut Fun Value event where Sans could appear as a patron in the Wild East's saloon, attempting to sell his seat to Clover for 30 G, then 300 G, before walking away. The game's art book elaborated that this event was first added as an in-joke for playtesters. Despite Spasco's desire to keep it in the final game, the event was ultimately cut because "it would've raised too many questions and implications for the story." The art book additionally contains sketches for an alternate version of the event where Starlo appears, asking if Sans is bothering Clover before Sans decides to leave of his own accord.

According to an "Ask the Developer" interview, there was internal debate on whether or not the remake should add a manual jump button, which was scrapped from the original version. They decided to implement it due to most modern players (such as those who played The Legend of Zelda: Breath of the Wild) having gotten used to Link being able to jump manually. Because of this, the way the jump attack functioned was changed to have two different methods of usage: one where it functioned the same as the original, and another where it could be done by pressing the attack button while jumping. This was due to the dev team being unable to decide on which method was better.

In Chapter 3, after Spoiler:Kris completes the final round of the Original Game on the Sword Route, Susie recounts Ralsei's experience growing frustrated at another video game in the Green Room. Afterwards, Ralsei states that "I was not very chuffed by that dart" in reference to an arrow hazard that appeared in the game. Later, in Chapter 5, Ralsei and Yellow's break in Flower Castle's cafe opens with Ralsei asking if Yellow has "any smoked herbs? Like, oregano," which Yellow misinterprets as "smokin' herbs." Both of these dialogue sequences reference a crude drawing of Ralsei smoking an oversized marijuana joint (traced over a preexisting edit of Super Mario 64 artwork) posted by Twitter user nlotch in 2021, which became a widespread internet meme following the release of Chapter 2. The Chapter 3 dialogue's wording additionally references a 2016 Facebook post by the account "Animals smoking Durrys", describing a centipede gripping a lit cigarette as "chuffin back a fat dart".

If the player loses the boss fight against Bane, one of the Game Over sequences that plays is Bane lifting Batman over his head and breaking his spine down on his knee. This is a reference to the 1993-1994 story arc "Knightfall"; the incident specifically took place in Batman (1940) issue #497.

Following its release, the fangame Undertale Yellow attracted public debate due to its soundtrack's use of preexisting songs and leitmotifs from Undertale, which caused videos and other related content to attract copyright claims from Materia Collective, the company which owns the rights to Toby Fox's music. Following a tweet at the start of 2024 where the developers explained that they would be working with Fox and Materia Collective to resolve the issues, Materia Collective CEO Sebastian Wolff posted a thread of his own claiming that the developers had failed to properly secure the necessary trademark, asset, and mechanical licenses needed to use the original game's music. When another user stated that Fox had provided "clearly defined permission for [Undertale's] music to be used" at the start of development in 2016, Wolff contested the claim, pledging to donate $10,000 to the developers if anyone could provide legally valid evidence of this that covers the full scope of alleged rights violations.

This prompted Fox himself to issue his own statement, relayed by Undertale Yellow's Twitter account on his behalf, stating that although Wolff was right in that they failed to secure permission "until very recently," he considered Wolff's bet to be "extremely unprofessional in a way I shouldn't have to explain." Fox revealed he had spoken to Wolff privately about the situation and advocated to help do right to well-meaning fans who made a mistake. Fox additionally revealed that he donated $20,000 to the nonprofit disability charity AbleGamers, as requested by Undertale Yellow's developers, to apologize for the fiasco, and stated that he would try to more concretely lay out the rights and licensing guidelines for Undertale's music in the future.

The limited edition of the Xbox 360 release of the game came bundled with a CD of the game's soundtrack, and a "mini massage strap" (a small wand vibrator that can be attached like a keychain) as pre-order bonuses.

On March 31 and April 1, 2003, seven young men in the city of Sturgis, Michigan placed at least 32 signs around local businesses, schools, banks, the city hospital and post office quoting a line from Zero Wing's infamous English translation as an April Fools' prank: "ALL YOUR BASE ARE BELONG TO US, YOU HAVE NO CHANCE TO SURVIVE MAKE YOUR TIME". Although it was a popular internet meme at the time, residents were not familiar with its origins and took offense. Sturgis Police chief Eugene Alli explained that the signs could be "a borderline terrorist threat depending on what someone interprets it to mean", and reported that the police station received numerous calls from concerned citizens and business managers about the signs, interpreting them as a homeland security threat related to the War on Terror. The group was arrested and charged with disorderly conduct, and released apologies to the press.

During Chapter 5, when Spoiler:several members of the Van Der Line gang end up shipwrecked on the tropical island of Guarma, Dutch and Arthur will be held at gunpoint by the local authorities. When questioned for his name, Dutch will give the false alias of "Aiden O'Malley", a direct reference to the character of the same name from Grand Theft Auto IV.

Using console commands, a player can re-enable the cut "Child at Heart" perk, originating from Fallout 3. Doing so reveals cut content which would have allowed a player to obtain the unique weapon Euclids C-Finder from Max in Freeside by passing a dialogue check with this perk. Max uses the line: "Reach for the sky, Mister!", referencing the Pixar film "Toy Story", but if Child at Heart was enabled, the player character's dialogue would consist of a second follow-up reference, this time to Buzz Lightyear.

A Kombat Kode (717-313) will display a message on-screen before beginning a fight which states: "RAIN CAN BE FOUND IN THE GRAVEYARD". As the ninja character Rain was only included in the game's coin-op arcade version as a prank by director Ed Boon, the Graveyard stage would have originally included rainy weather effects but was cut from the final release. This planned effect was able to be recreated after raindrop sprites were found in a 2023 source code leak.
