The GameCube release contains the SNES game Super Punch-Out!! as a bonus game. Completing the game will unlock Little Mac from Super Punch-Out!! (distinguished by his intro from the ring announcer as being from Tokyo, Japan, whereas the Little Mac in all other entries in the Punch-Out!! series is from the Bronx, New York) as a playable character. Little Mac can also be unlocked by naming a custom boxer "Macman" and saving the end result. This cameo was part of a deal between Nintendo and EA that allowed them to use Nintendo's characters for three of EA's games for the GameCube, the other two being SSX on Tour and NBA Street V3.
During the beginning part of Sephiroth's Supernova Final Smash where everyone turns to the Z-Axis to view Safer Sephiroth, the normally "flat" Mr. Game & Watch can be seen as a 3D model if he is caught in the attack.
In the Japanese release of the game, pineapples, strawberries, melons and watermelons are classed as a vegetable and cannot be given as a present at the Fruit Fiesta event. This error was fixed for the North American release at the request of publisher XSEED Games because it would be too confusing to Western players who generally view these crops as fruits.
When ported to the PC Engine, the game's name was changed. The Japanese release was known as Adventure Island, not to be confused with the Hudson Softseries of the same name, and the North American release was known as Dragon's Curse. A Game Gear version was also released in Europe under the game's original title, and in Japan under the name Monster World II: Dragon no Wana.
In story mode, Sticky Fingaz and Method Man can be seen playing the game itself based on the console version the physical copy is being played on: •The PlayStation 2 version will show them both playing the game with DualShock V2 controllers •The Xbox version will show them both playing the game with Xbox S controllers. •The GameCube version will show them both playing the game with Nintendo GameCube controllers.
This is the only entry in the Super Smash Bros. series that lacks an opening cutscene once it is booted, which was likely done to save space on the game cartridge.
Exclusive only to the Wii U and Nintendo Switch ports of the first two games in the series, several costumes were added that are based on Nintendo characters with additional features tied to them:
•Both the Mushroom Kingdom Princess and Sarasaland Princess costumes resemble the princesses Peach and Daisy from the Mario series, with Mario and Luigi charms attached to their dresses respectively. Coins will drop instead of Halos once enemies are defeated and collecting them will play the coin sound effect from the series. Attacks that summon Madama Butterfly are now replaced with Bowser's hands and feet.
•The Hero of Hyrule costume resembles Link from The Legend of Zelda series. Equipping the Shuraba with this costume will turn the current weapon into the Master Sword. Wearing the costume replaces the Halos with Rupees as well as the standard sound effects with those from The Legend of Zelda: A Link to the Past, specifically because it is series director Hideki Kamiya's favorite Zelda game. If Jeanne wears the costume, sound effects from the The Legend of Zelda can be heard instead.
•The Galactic Bounty Hunter costume resembles Samus Aran from the Metroid series. Samus's blaster cannon can be used without needing to equip a weapon skill. Furthermore, Samus' visor works differently between the two games.
•The Star Mercenary costume exclusive to Bayonetta 2 resembles Fox McCloud from the Star Fox series. Equipping the Love is Blue/All 4 One with this costume will turn the current weapon into Arwing Guns, each having charms that resemble Fox, Falco, Peppy, and Slippy. If Bayonetta dons the costume, sound effects will be replaced with those from Star Fox 64. However, if Jeanne dons the costume, sound effects from Star Fox will be heard instead.
•The Chain Chomp foot weapon, also exclusive to Bayonetta 2, can be obtained by completing all chapters on Hard difficulty. The Super Mario 64 Golden LP can be given to Rodin and he will give Bayonetta the Chain Chomp, which plays sound effects from that game. Upon performing the Umbran Dance with either Bayonetta or Jeanne will give them Mario and Luigi's caps with both letters replaced with the letter B and J, while also having fake mustaches.
The DLC, "Legacy of the First Blade, Shadow Heritage", was the subject of controversy and backlash from the LGBTQ+ community. At the end of the DLC, the player character was forced to be part of a heterosexual relationship, ending with the player character having a child with another character. Many players saw this as a disservice to the LGBTQ+ community, and Ubisoft going back on their commitment of diversity and inclusion within the game. Despite allowing the player to choose their sexuality through multiple romantic encounters throughout the game, the DLC gave no option to decline the relationship, forcing players to engage in the heterosexual relationship. Furthermore, completing this unlocked an achievement titled, "Growing Up". The developers apologized and released a patch for the DLC. In the patch, the ending is still the game, and a baby is born, but the player character is allowed to clarify that they choose to do so to "further their bloodline", and not for romantic reasons. The title of the achievement was also changed to "Blood of Leonidas".
According to Platinum Games artist Yong-Hee Cho, Bayonetta's director Hideki Kamiya requested concept art of Bayonetta in Princess Peach's costume for the Wii U version. In addition, Kamiya also requested Cho to design a Mario Charm for Peach's costume and a Luigi Charm for Daisy's costume, and pulled Bayonetta's long black locks in favor of flowing fabric.
Cho also goes on to talk about the concept for the Link and Samus Aran costumes, with the second costume being based on the NES original. According to Cho, it was actually Nintendo who pushed for Bayonetta to show a bit more skin while dressed in her Link costume.
Additionally, Bayonetta in her Samus Aran costume was at one point given the ability to form into a Morph Ball like how Samus does in the Metroid series, but the idea was scrapped and instead was later implemented in the game's sequel, Bayonetta 2.
An unused enemy named "Gotouryu", a Flying Demon based on the Japanese yōkai of the same name, can be found in the data for the Wii version. When asked about why the enemy was cut, director Hideki Kamiya admitted that he forgot to add the enemy in the game.
Sora, Kairi and Riku's ages at the chronological time of this game's story are all stated in the PlayStation 2 release's instruction manual. Specifically, Sora and Kairi are both 14, and Riku is 15.
After footage of the game's final boss surfaced from pre-release copies, players expressed concern to the developers that some intense rapidly flashing lights and other visuals during the final boss may cause serious seizures to players that have photosensitive epilepsy, and in general may be an eyesore to players that are not epileptic. The developers understood and significantly changed the battle effects in a day-one patch that was heavily recommended by Square Enix to be downloaded by future players.
When bringing the series to the west, publisher XSEED Games revealed the developers almost named the series "Ninjugs", before deciding to keep the Japanese name Senran Kagura in the end.
According to a Japanese Seiken Densetsu guide book (specifically, the one with the blue bottom and "SQUARE BRAND" in the bottom right corner), one of the game's programmers claimed that it apparently began life as an experimental tennis game.
"This game actually started out as an experimental tennis game. At some point, the court turned into scrollable screens, the racket turned into the playable character, the ball turned into a weapon, the opponent’s racket turned into enemies, and the “court” became referred to as the “map”… And before I realized it, a story was added into it and then the game was released as “Seiken Densetsu.” It was a curious experience."
In the European release, the Mini Mustache accessory is altered from a toothbrush mustache to a pencil mustache. This change is most likely due to the toothbrush style's association with German dictator Adolf Hitler.
Kingdom Hearts' international release is the last game by Squaresoft released outside of Japan to have their logo and name adorned on its case before the company merged with Enix to become Square Enix in 2003. The Japanese version of Final Fantasy X-2 was last game ever to feature the Squaresoft logo in any region.
After defeating the final boss, Modern Tails & Classic Tails are briefly seen discussing something at Sonic's birthday party during the game's last cutscene. What they are talking about differs between the English and Japanese localizations of the original game.
In the English version, they said: Classic Tails: He collects how many? Wow, where does somebody put all those gold rings? Modern Tails: You know what? I don't know. I keep forgetting to ask.
In the Japanese version, they said: Classic Tails: You added legs to the plane? What have you done to Sonic's Tornado? Modern Tails: Yeah... I guess really did go overboard with the legs...
In Sonic X Shadow Generations, the English version of this cutscene was completely re-recorded by the original voice cast, where they now say: Classic Tails: So I have a question for you. Once we're home, you think the timeline will be restored? Modern Tails: Yep! Just... don't think about it too hard.
Before the game series was cancelled by Disney, a fourth installment was quite elaborately planned and worked on extensively. The name would've been "Disney Infinity 4.0: Kingdoms" and it would have primarily been based of Disney's animated film Aladdin. It was to be developed by United Front Games who are associated with working on the Marvel expansion of Disney Infinity 3.0 as well as Sleeping Dogs, ModNation Racers, and Halo: The Master Chief Collection. It seems the game would have had a feature where characters of unrelated universes (ex. Star Wars, Marvel, Zootopia, etc.) can be played and seen in the Aladdin-based Story mode, which would have been unique to 4.0. (Although it does bare some resemblance to the Toybox Takeover feature in the previous game.) Pre-alpha footage of the game was uploaded to Vimeo in November of 2018 by a throwaway account, revealing the game's existence.
According to game's director Hideki Kamiya, the Umbrella Corporation can that gets stepped on at the start of the opening cutscene was supposed to have the Capcom logo on it, but when Capcom's management heard about it, they disapproved of the idea of their brand being stepped on, so the developers changed it to the Umbrella logo instead.
An update released three days before the game's 10th anniversary on April 26th, 2018 added new songs to radio stations, while simultaneously removing songs due to licensing-expiration issues. Among the many song replacements, the Electro-Choc, Fusion, JNR, Massive B, and Tuff Gong radio stations remained untouched, while almost every song featured in the Vladivostok FM station was cut and replaced with new songs with one exception, "Liberty City: The Invasion" by Seryoga, an original song written for the game's soundtrack. These changes also carried over to the Episodes from Liberty City DLC expansions.
