PlayStation PC games should work on ROG Xbox Ally despite doubts

Unless Sony finds a loophole, the ROG Xbox Ally handhelds should be able to run PlayStation games at launch. That's thanks to the handhelds' compatibility with Valve's Steam storefront, allowing them to access Sony's PlayStation PC games. However, there are still a few doubts that need clearing up before we know for certain which games will work.

There's really only one source of hesitation regarding PlayStation games running on the Xbox Ally handhelds, and it comes from a point raised in a tweet from Windows Central's Jez Corden. In his post, he implies that Sony might be able to block its games from working on Microsoft's handheld as they've done something similar before with Nvidia's GeForce Now service.
In case you weren't aware, GeForce Now is a cloud streaming service that can run on multiple devices via an installed app or even directly through an internet browser (this latter option even lets some users access it via Xbox Series X|S's Microsoft Edge browser). Initially, the big sell for the service was that it let you stream your full Steam library on any device — including Sony's PlayStation games on Steam.
