Rape Day
The most well-known case is the visual novel Rape Day, which was listed on Steam in March 2019 and quickly removed before its release.
The game was a visual novel about a serial killer who rapes and murders women during a zombie apocalypse.
Developer Desk Plant attempted to defend the game, but international outrage and petitions led Valve, Steam's owner, to remove the game, citing "unknown costs and risks".
No Mercy
In April 2025, another highly publicized incident involved the game No Mercy.
No Mercy allowed players to "assume the persona of a man who rapes his female family members" and was heavily focused on incest.
Despite widespread condemnation, including a petition signed by 70,000 people, Steam initially did not remove the game.
After the game was banned in the UK, Canada, and Australia, developer Zerat Games eventually removed the title voluntarily.
In response to the controversy and a campaign targeting payment processors, Steam later updated its rules to better filter this type of content.
Other adult titles
In the aftermath of the No Mercy campaign in July 2025, a gaming advocacy group reported that after contacting payment processors, hundreds of other adult-only games depicting rape, incest, and child sexual abuse were removed from Steam. Steam's updated policy now prohibits "Content that may violate the rules and standards set forth by Steam's payment processors".
As of July 2025, Steam has not published a specific, definitive list of removed "hentai school games," but a number of titles were delisted as a result of a major policy change. The games were removed not because of the "school" setting, but rather because of pressure from payment processors over sexually explicit content, particularly titles referencing incest or similar taboo subjects.
While it's impossible to provide a comprehensive, officially sanctioned list, here is what is known:
No specific list: Steam does not provide an official list of removed adult games, and the database tracking website SteamDB is the main source for this information.
The policy shift in 2025: In July 2025, Steam modified its guidelines to prohibit "certain kinds of adult-only content" that could violate the standards of its payment partners.
Targeted content: Dozens of games were subsequently delisted, with SteamDB reporting that many titles referencing "incest" or other controversial themes were removed.
Hentai school games were not specifically targeted: Being a "hentai school game" is not an automatic cause for removal. While school settings in adult games were once a point of concern for Valve, the recent purges were aimed at more specific content themes deemed problematic by payment processors.
"Love Ribbon" DLC removed: The developer for the incest-themed visual novel Love Ribbon had its 18+ DLC removed from Steam, although the base game remains available.
The 2018 ban: Years before the 2025 removals, developers of games such as Cross Love and The Key to Home faced bans partly due to local Washington obscenity laws, which led to confusion over depictions of young-looking characters in a school setting.
Broader content concerns: Games with themes of "non-consensual sex" and other controversial topics have also faced removal, such as the title No Mercy, which was delisted in 2025 after a public campaign by the organization Collective Shout.
Slave Secretary: This adult-themed visual novel was published on Steam in July 2025. However, its presence on the platform does not mean that all games of this nature were spared, and it may have been added after the major delisting event.

The world shouldn't have the right to demand that an app or website, which caters to a diverse range of gamers of different ages, remove adult content; it's a matter between the developer and the owner of the platform. The owner of the platform and developers should debate what is allowed on sites like Steam or Itch.io, and then it's up to the platform to enforce the rules.
Valve, owner of Steam, Gabe Newell, is the CEO and co-founder of Steam. He should have the right to tell what’s allowed to be published on his platform and talk with the developers, take the video game down, it’s his platform, not PayPal and Master cards.
The world should have the right to take down adult video games that have incest, rape, cheating, slavery, and characters who are young men and women. At the end of the day, it’s a video game; nobody was harmed.
I would like Rape-lay, Rape Day, and No Mercy to be on Steam; it’s between Gabe Newell and the Developer or publisher.
When this is over, I would love adult games, not need a content patch because going to another platform to download it, or downloading on Steam, is annoying. Just say it’s rated Adults, there is an adult section, and you need to reach a certain age to see that kind of content. I hate that developers have to change character relationships because activists say this promotes incest, rape, and child abuse, but we all know they don't care about women and children, since they said nothing about Roblox and their Co-workers for liking CSAM.
It’s ruining developers’ right to be creative, and we all know what kind of people complain about video games, we find out they have CSAM on their computer. Which is ironic, a players who play adult games might not have a criminal record, but a bigot activist and double standard world would have a criminal record.
Why we should return adult games because it’s freedom of speech and should be between the owner and developers, even the publishers, to talk it through, not the people who aren’t going to buy it at the end of the day, it’s a product.
