The Xbox 360 port of the game natively supports the ability to use custom music in place of the game's original soundtrack. When music is played through the Xbox 360 Dashboard, the original soundtrack is muted and replaced with the player's loaded soundtrack.

When the player goes into the Batcave, there is a chance that Alfred will say: "Why do we fall, sir? So that we can learn to pick ourselves up. Batman Begin." Besides referencing a quote from the 2005 movie "Batman Begins", this lampoons a tweet made by Alfred's actor in the movie Michael Caine, where he quotes the line while including "Batman Begin", making it seem as if the movie's title is part of the quote itself.

After completing the Chapter 2 story mission "On the Prowl", a side quest becomes available where Batman has to find and put trackers on 21 escaped zoo animals. When the player acquires a few of these zoo animals and talks to one of the male Zoo Workers, he will erroneously refer to the Joker as "the Jonkler". This is a reference to a meme misspelling the Joker's name that originated from the subreddit r/BatmanArkham in 2023.

When loading a chapter in console releases, the game displays an animation of the Annoying Dog being lowered onscreen via a rope, reusing sprites from one of Papyrus' traps in Undertale while adding additional ones to cover a full 360 degree rotation rather than swaying 180 degrees back and forth. The PC release also contains a fully coded version of this animation, but it goes unused due to chapters loading far more quickly, at around 4 seconds.

The trailer for the game incorrectly refers to platypuses as duck bills and seals as sea bears. It's possible though that this could be a translation error. The game's developer BrainGame is based in Germany, where platypuses and seals are referred to as schnabeltier ("billed animal") and seebär ("sea bear") respectively. These were two of the earliest names given to platypuses and fur seals when they were discovered by humans.

According to executive producer Robbie Daymond, choosing the game's environment was a major factor when approaching the game's concept. When it was decided that the player character would be a shut-in who didn't get out much, they incorporated this into both the plot and the game mechanics, as the player is a person who doesn't leave their home by choice. Early on, the game was planned to have escape room elements where the player is held in their house by an unknown force, but this was dropped in favor of a sandbox approach due to the team believing it wasn't much fun and made the game too linear.

The information describing kangaroo joeys says that they only leave their mother's pouch after 8 months have passed. This is only accurate for the red kangaroo, as other species such as the grey kangaroo can remain in the pouch for up to 11 months.

While the game's box art shows Lucy in a blue form-fitting dress, a recurring running gag throughout the game is that she is portrayed as a nudist. The dress she wears on the box art splits apart during the game's opening cutscene (as well as in the Lucy audition trailer) and she is nude for the remainder of the game, having three blue censor bars cover her breasts, crotch and buttocks. However, removing the censor bars reveals that besides her buttocks being fully textured, Lucy lacks a vulva and nipples.

When designing the eight playable characters, the developers decided to base them off of the seven deadly sins, while the game show host Van Tastic represented "pure evil". Lead programmer Michael Saladino recalled that they intended to turn the game into a franchise with licensable characters and were designing them as such, but they soon fell into a creative rut:


They found that the leeway they gave to the character designers came at the expense of other departments, in particular the texture artists who had to pull all-nighters to finish their work as the designs were not delivered soon enough. Before deciding on Eugene, other early design concepts for the envy character included a "green-eyed monster" (in reference to an idiom for envy), an elderly lady with a talkative internal voice, and a short basketball player with robotic limbs.

The character design of Spoiler:Asriel, as depicted during the Pacifist Route's final battle, appears to draw heavily from Sariel, the final boss of the 1996 game Touhou Rei'iden: The Highly Responsive to Prayers. Both characters' names can be read as anagrams of one another and draw from archangels in Abrahamic mythology: Spoiler:Azrael is the Islamic archangel of death and is named in the apocryphal Apocalypse of Peter as an avenger of the wronged, while the Judaic archangel Sariel is mentioned in the apocryphal 1 Enoch 20:6 (under the Ethiopic rendering "Saraqâêl") as "set over the spirits, who sin in the spirit." Additionally, both characters feature a predominantly white color scheme save for a long robe with a white symbol on it; as Toriel's version of this robe is deep purple, like Sariel's, it is consequently implied that Spoiler:Asriel's robe is the same color.

Goat Simulator 3 is the direct sequel to Goat Simulator, but was intentionally not called "Goat Simulator 2"; there is no game in the series with that name. In interviews with the game's developers, contradictory joke answers were given regarding the reasoning behind the title. These included:

• That they somehow lost track of the second game.
• That they were choosing not to release the second game.
• That they were unaware of Goat Simulator 3's title.
• That the game's title was a compromise between the choice of naming the game "Goat Simulator 2" or "Goat Simulator 4".
• That they thought they had made "Goat Simulator 2" already and only realized after the fact that it never existed.
• That "Goat Simulator 2" had been a horror game released in 2017, but players were repressing the memory of the game due to their sheer terror.
• That it was a typo, and that they meant to name it "Goat Simulator 4".

Both MotoGP Ultimate Racing Technology and Whacked! were the first Xbox games to support Xbox Live prior to the service's launch on November 15, 2002. Whacked! was also the first game to pass Xbox Live release certifications, and both games had online demos in the Xbox Live Starter Kit. Whereas Whacked! had online support out of the box, online support for MotoGP Ultimate Racing Technology was limited to the demo disc and had a smaller amount of content. If players wanted to import more tracks and customize bikes for the online mode, they would have needed to have save data for the full game on the Xbox's hard drive to unlock access to the rest of the base game's content online.

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."
