Shortly after its release onto the Nintendo Switch, the game was removed from sale from the North American Nintendo eShop due to containing content deemed beyond acceptable for the ESRB rating it was given. It was re-released on March 20th, 2020 as Lust for Darkness: Dawn Edition with the explicit content and sexual imagery toned down. The European release however remained unaltered with the "Dawn Edition" also added to the European Nintendo eShop.

A Doctor Who video game by Australian studio IR Gurus (later Transmission games) was in development but canceled due to complications. The game was to coincide with the first series of the revived show starring Christopher Eccleston and Billie Piper. Development went for half a year and funded through substantial government subsidies. According to Paul Callaghan who worked at the studio, a possible plot he conceived was that airborne nanobots released by aliens were modifying the human race which included the Doctor's companion Rose Tyler, enabling her to have "...some cool alien powers!"

However, according to then BBC Worldwide head of communications Andy Widger, there were no intentions of releasing the game as it was just "an interactive demo for internal evaluation."

Jun Senoue, famous for being a lead music composer for Sonic Adventure 1 and 2, said he was insipired to write and arrange Super Smash Bros. Ultimate's "Mega Man 4 Medley" in the style of a Sonic Series composition after he came across a Sonic and Mega Man crossover comic that sparked his imagination. He chose to center his arrangement on the 4th Mega Man game because of fond memories that he had of playing the game at university.

The iconic start-up sound of the PlayStation is actually a combination of three different clips stored in the system BIOS, which are then either sped up or slowed down to produce what is heard at the boot-up screen.

Arch Hammer is known within the Warhammer community for his misogynistic, racist, and hateful remarks. In a statement from Wargaming on July 3rd 2020, they issued an apology and claimed that sponsoring Arch was due to "human error" and had since cut ties with him. They even admitted that they were warned beforehand by Warhammer's owners Games Workshop not to collaborate with him but had failed to follow their request.

In an update for the game released in November, 2020, two in-game podcasts featuring journalist Helen Lewis were replaced by Ubisoft after receiving complaints from concerned gamers. This was due to Lewis being known in the public for having transphobic views and writing a number of articles criticizing legislation which were in support of making gender transitioning easier.

Ubisoft told in a statement that the speaker profiles for the scripted in-game podcasts were chosen by an external producer that worked with the development team. They promised that in future they'd perform background checks on any future partners.

The Game Boy Advance version was originally intended to be a straight port of the original Sims game for PC, however this wasn't possible as the simulation gameplay of the Sims didn't translate well to the hardware. Instead, inspired by the first console version of The Sims where players could follow their Sim's story in a more personal way, the game's producer J.C. Connors pitched to EA what would become Bustin' Out on the Game Boy Advance.

A Nintendo Switch version of the game was planned and even worked on, but, according to the Steep twitter account, this Switch release was canceled in order for the development team to focus on creating more content for the other console versions of the game.

The game has two different titles between the North American and UK versions. In the US the game is referred to as Clubhouse Games: 51 Worldwide Classics, whereas in the UK it's called 51 Worldwide Games. Another change is that Checkers and Toy Soccer are called Draughts and Toy Football respectively in the UK version.

In 51 Worldwide Classics, there's a Golf Game which has up to 9 Holes. When looking closer at all the holes, they seem to show a striking resemblance to the first 9 Holes from Golf in Wii Sports, and in turn many holes from the NES game Golf.

The Sombrero Guy from Autumn Mountain may have been planned to be a temporary party member just like Spike and Bone Goomba, but was left out. Altering the code through save file hacking makes the character fully functional and adds an otherwise unused graphic to the pause menu.

Found on one of the movie theater marquees is the message "Maddie, Will You Marry Me?" This was an Easter egg included in the game at the request of fan Tyler Schultz who tweeted out to Insomniac asking them for help with his marriage proposal to his then girlfriend of 5 years Madison Gamble ("Maddie" for short) by including the message somewhere in-game. However, by the time the game had released, Gamble had broken up with him with Schultz explaining what had happened. Insomniac had offered to patch out the message but Schultz requested to keep it in as a reminder for "the almost mistake that I made." adding that his girlfriend told him "that the video game message wasn’t the way she wanted to be proposed to, either."

Gamble would later say in a statement that she never even liked video games and only tolerated them because of Schultz. She claimed that she broke up with Schultz due to his behavior and gave him a month to change but to no avail.
