Although the game makes no mention of it, completing each chapter again after finishing Emerl's episode will reward the player with a page from Spoiler:Professor Gerald Robotnik's journal which documents Spoiler:his discovery and subsequent experiments on the Gizoid.
At the start of Bayonetta, a funeral is held for a notorious criminal known as "Eggman the Destroyer". This, to a Western audience, seems like a very obvious reference to Sonic the Hedgehog's main antagonist Dr. Eggman, as Bayonetta was published by Sega. However, series creator Hideki Kamiya claimed that he randomly chose the name Eggman and was not aware that there existed a popular Sega character with the name, choosing to leave it as is in the hopes that fans would "get a kick out of that".
When setting a profile on Nintendo World Championships: NES Edition, you can choose a favorite game from a near-comprehensive list of official NES/Famicom games released within the console's original lifespan, including games made by third parties, regional retitles, and even licensed IP games. As a result of this, it marks the first time since their release that Nintendo has officially acknowledged Mario is Missing! and Mario's Time Machine, a pair of third-party Mario educational games, discounting a vague and dismissive unnamed acknowledgement in Super Smash Bros. Ultimate.
The jubeat series utilizes a scoring system to determine its ranks and whether a player clears or fails a song, with notes scoring points depending on how close they are to a Perfect timing. At least 700,000 points are required to get the lowest passing grade of C. This means it is possible to obtain a full combo yet still fail a song through lack of points by intentionally hitting all notes early/late enough to still register as a Good.
In a 2018 Syfy Wire interview with writers Christos Gage and Jon Paquette, they revealed that Silver Sable and Sable International were included in the game because they felt that there needed to be a presence or force in the overworld that added more stakes and tension to the game once the story events "became dire".
To promote the release of Zenless Zone Zero, publisher HoYoverse collaborated with several graffiti artists to create graffiti based on the game across nineteen different cities in Indonesia.
While Samurai Deeper Kyo received a formal release in Japan in 2002, it was never actually released in stores on its own in North America, instead being included as a bonus in the source material's complete series DVD box set in 2008. This made the North American version of the game the last officially licensed game released for the Game Boy Advance.
According to programmer Dylan Cuthbert (who reportedly help named the original pilots from the first Star Fox), one of the new pilots in Star Fox 2, Fay, was named after his childhood crush, a girl who lived next door to his grandparents' house. Although Fay, as well as Miyu, were never officially given proper surnames, Cuthbert has stated that in his head, he's always considered their full names to be Fay Sinclair and Miyu Swift respectively.
Within the Underground World (a hidden area in the Dream World only accessible by sleeping in one of five replicas of Madotsuki's bed, randomly chosen each time she falls asleep) is a large corridor full of fire. Normally, this room requires Madotsuki to obtain and equip either the Snow Woman or Umbrella effect, which produces precipitation that puts the fire out and allows her to proceed into the Storage Room. However, if she enters this area as a snowman (by equipping the Hat & Scarf effect and pressing the 1 key in the Snow World) and stands next to the fire, she will slowly melt into a puddle of water; pressing the 1 key while in this state reverts her back to human form, as with the un-melted snowman.
While Madotsuki can also become a snowman in the blizzard generated by the Snow Woman effect, the weather would carry over to the corridor and extinguish the fire immediately upon entering. Consequently, Madotsuki can only access this Easter egg via the blizzard that appears by default in the Snow World.
In September 2020, it was announced that the game's original director and series creator Michel Ancel would be retiring from the video game industry to focus on working for a wildlife sanctuary, but it was assured that development would continue without him. Later that month, the French newspaper "Libération" reported that several members of his team at Ubisoft Montpellier had accused him of acting abusive and unorganized, resulting in numerous delays and restarts since the game's announcement in 2008. This behavior was allegedly worsened by his simultaneous work on Wild (a big-budget game announced in 2014), preventing him from working on Beyond Good & Evil 2 with its team full-time. Although reports were submitted to company leadership as early as 2017, it was alleged that Ancel's relationship with Ubisoft co-founder Yves Guillemot prevented any major corrections from occurring until June and July 2020, when employees from all over the company came forward with sexual abuse and other misconduct allegations against high-ranking executives. Ubisoft would later comment that Ancel had not been directly involved in the game's development for "some time now" before his departure.
Ancel was interviewed as part of Libération's investigation. He claimed that Guillemot informed him that Ubisoft was investigating him in early August 2020, but claimed he was unaware that numerous team members blamed him for the game's development issues, and believed they were actually caused by long-term stress and burnout. He claimed he resigned on his own accord and that his only regret was not finishing the game sooner. The newspaper claimed that the interview took place on September 18th, the same day that Ancel and Ubisoft's statements about the departure were released. One week later when the report and interview were published, Ancel denied all of the allegations in an Instagram post, calling the articles "fake news" and accusing the newspaper of publishing them as soon as possible to conflate them with the earlier Ubisoft allegations in June and July, over a month before Ubisoft's investigation into him allegedly began.
There is a miniature model of Lloyd the Lion located in the back of the Lloyd's Main Stage Theater area. According to the game's creator UniqueGeese, he couldn't remember why exactly it was there, but theorized that he was simply testing the model and forgot to remove it due to how small it was. He added that he likely won't remove it because "it took forever for people to find it."
The Kentrosaurus notably has a unique quirk in that it will panic if placed in the same enclosure with other large herbivores, barring some exceptions like the Stegosaurus. This is in contrast with the Prima guidebook that makes no mention of this behavior and even recommends to house the Kentrosaurus with all other herbivores in the game, which suggests that this was either a glitch or an oversight on the development team's part.
Several additional characters were planned to appear in the game, but were scrapped in order to keep the game's plot easier to understand. This includes the presence of a "Space Broadcasting Censorship Bureau", who would interrupt broadcasts that were deemed unsuitable (and whom Pine was originally going to be a member of alongside her backups Sexy 1 and 2, taking issue with Ulala's exposing outfit), a narcissistic reporter from Channel 777 named "Gold Kinpicano", and a different main antagonist tentatively referred to as the "Dark Dancing Demon Lord", whose goal was to invade the entire universe with dance.
Red Dead Revolver originally began development with Capcom in 2000, when developer Rockstar San Diego was still known as Angel Studios. It started as "SWAT", a game with a four-person split-screen feature that allowed you to control four members of a S.W.A.T. team at once. Reportedly, after Capcom producer Yoshiki Okamoto watched the 1971 spaghetti western film "Blindman", the project quickly shifted to a western game, with "SWAT" now standing for "Spaghetti Western Action Title" before being renamed to Red Dead Revolver. After Angel Studios was acquired by Take Two Interactive in 2002 and renamed to Rockstar San Diego, they continued working with Capcom on the project until Capcom decided to cancel the game in 2003 due to a perceived lack of progress. Capcom eventually agreed to let Rockstar Games continue working on Red Dead Revolver the same year in exchange for having exclusive publishing rights in Japan.
Kien was originally developed between 2002 and 2004 by AgeOfGames, a group of five Italian developers who had no prior experience making video games, aiming to be the first company in their country to develop a game for the Game Boy Advance. The game's release would end up being cancelled three separate times when multiple publishers picked up the game and then decided that releasing it would be too risky for sales. At the time, the game was completed and sent to gaming publications, with one known review appearing in the American magazine Nintendo Power in 2003. The game remained unreleased for over 20 years, but a prototype ROM of the game did leak online at one point. Game designer Fabio Belsanti would be the only member of the game's original development team to remain at AgeOfGames, who had shifted to developing educational games to stay afloat. Eventually, with the rising popularity in retro games and lowered cost to produce GBA cartridges, AgeOfGames was able to release Kien in 2024 both digitally and on physical cartridges through retro game publisher Incube8 Games. The game's release garnered attention for it possibly having taken the record for the longest delayed video game release in history, surpassing Duke Nukem Forever and Beyond Good & Evil 2 by taking 22 years to release.
The character of NiGHTS was inspired by director Naoto Ohshima's travels across Europe and western Asia. In order to give his design as much universal appeal as possible, various regional styles were incorporated into it, namely Japanese, European, and American. In the context of the game, NiGHTS is part of every person's subconscious, and as such was designed to have an androgynous "dual male/female" appearance, but has been referred to with male pronouns in the same breath by Sonic Team.
The existence of Nintendo World Championships: NES Edition was accidentally leaked ahead of its official announcement by the ESRB website on May 3, 2024.
In 2023, the game's official Twitter account hosted a poll to decide the name of a character set to be added to a future "Beach Bash" event (the character was tentatively named "Crab-chan" on account of her being "literally a crab turned into a waifu"). The options given were all crab-based puns: "Crabitha" (a portmanteau of "crab" and "Tabitha"), "Shelly" (a reference to how many species of crab have shells), "Pearl" (a nod to how crabs are capable of creating "pearl sacs"), and "Crabigail" (a portmanteau of "crab" and "Abigail"). The name "Shelly" ultimately won, and she was added to the game as part of the Beach Bash Event 2024.
In Amy Rose's official render for the game, the bottom of her left leg can be seen clipping through the side of her boot.
