Sony reportedly planned to offer PlayStation Now on smartphones
Sony might have been another console maker looking to bring the experience to smartphones. In a document obtained from Epic Games' lawsuit against Apple, the iPhone maker reportedly learned about Sony's plans to have a "mobile extension" of PlayStation Now back in 2017. It intended to stream over 450 PS3 games first, followed by PS4 titles.
Apple mentioned this rumour/report in the middle of explaining its plans to launch its game subscription service. It didn't launch Apple Arcade until a couple of years after that, but the company saw it as a shift in the industry towards gaming subscriptions.
