Sony may have jumped the gun when it said only 10 PS4 games would not be backwards compatible with the PlayStation 5

On Friday, Ubisoft said nine of its own past PS4 titles are not compatible with the upcoming console. The titles include: 

  • Assassin’s Creed Syndicate
  • Assassin’s Creed Chronicles Trilogy Pack
  • Assassin’s Creed Chronicles India
  • Assassin’s Creed Chronicles China
  • Assassin’s Creed Chronicles Russia
  • Risk
  • Star Trek Bridge Crew
  • Werewolves Within
  • Space Junkies.

Ubisoft’s blog post doesn’t dive into details. So it remains unclear if the games simply won’t boot over a PS5, or if the gaming experience is too buggy, making them unplayable. 

The real issue is how the blog post casts doubt on Sony’s claim that “more than 99 percent of PS4 games will be playable on PS5 on day one.” According to Sony, PS5 owners will be able to enjoy more than 4,000 PS4 titles on the new console when it arrives Nov. 12. To play them, you can slot in a PS4 disc into the PS5’s Blu-ray drive, or download from the PlayStation Store. 

The only exceptions to the backwards compatibility, Sony said, were 10 games—none of which are hugely popular. However, Ubisoft’s blog post suggests the list should expand to 19. 

We’ve reached out to Sony and Ubisoft for comment, and we’ll update this story if we hear back. But in the meantime, Sony’s support document on the games not compatible with the PS5 does note: “This list is subject to change and excludes demos, media, and non-game applications.”

At the same time, Sony has acknowledged the backwards compatibility won’t always run smoothly. “Some PS4 games may exhibit errors or unexpected behavior when played on PS5 consoles,” the company added in the official support document.

Meanwhile, Ubisoft is pointing out that its Xbox One games are all backwards compatible with the upcoming Xbox Series X and Series S consoles, without elaborating.

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.
