Steam appears to be cracking down on games with anime-style art and sexual content.

On Thursday, several game developers tweeted that Steam had flagged their products for porn and ordered them to remove the problematic content. If they did not, their titles would be pulled from the platform.

The developers say they have two weeks to fix the problems, even though their adult-oriented games have been on digital store for months, if not years.

All of the affected titles feature anime-drawn characters and some nudity. Many also contain overtly sexual imagery. But the content has hardly been a secret; to abide by Steam's policies, the games have been labeled to say they do contain sexual images.

In addition, Steam has a category specifically devoted to games with sexual content.

Why is the platform suddenly taking a hard line on these games? Valve, the company behind the digital store, has not commented. Although pornography isn't permitted on the platform, adult content that's been appropriately labeled and "age-gated" is, according to Steam's own guidelines. That's provided leeway for certain adult-oriented games on the store, some of which have gained thousands of positive reviews.

The developers say they're in the dark over why Steam suddenly reversed course. One publisher, MangaGamer, said it had taken "great pains" to run its own title by Valve representatives to ensure none of the content would be considered porn. But now it appears that at least eight games will be affected by the upcoming crackdown.

In a tweet, the developer Lupiesoft said Steam was singling out anime-style games for sexual content, when hit titles from US developers that also feature nudity and sex have been left "unscathed" by the upcoming change.

"Games are being pulled simply because they look a certain way and there is a stigma behind the look of a game," the developer added.

However, Steam isn't the only platform to take a stricter stance on porn in recent months. Back in October, crowdfunding service Patreon also unveiled new rules against porngraphy, causing many developers to complain.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
