Sony Group Corp. no longer plans to release its big PlayStation 5 games on PC, a major shift in strategy that sees the video-game maker returning to console exclusivity after six years of flirting with multi-platform releases, according to people familiar with the company’s plans.

Online games such as Marathon and Marvel Tokon will still be released across multiple platforms, but single-player titles such as last year’s samurai hit Ghost of Yotei and the upcoming action game Saros will remain exclusive to PlayStation 5, said the people, who asked not to be identified because they weren’t authorized to talk publicly about the company’s strategy.

Also Schreier's additional take:
