You will soon be able to open non-Xbox games from the Xbox app, which could be a great way to further avoid the Epic Games Store
With the ROG Xbox Ally X and Xbox Meta Quest 3S on the horizon, Microsoft is going some way to upgrade its software on non-Xbox-made hardware. Perhaps the biggest and most useful push so far is the upcoming ability to play non-Xbox games straight from the Xbox app. Unlike the former hardware collaborations, this, I might actually use.
Announced via Xbox Wire, Xbox Insiders will be able to boot up games from "Xbox, Game Pass, Battle.net and other leading PC storefronts" all directly from the Xbox app.
