Different market the gaming platform on PC isn't tied to a sole entity you dont even need windows to play games you have linux,ubuntu,steam os,Ios. Pc has multiple store fronts and multiple distributors no one person owns anything steam is less a store front and more of an open internet data base for games were you can do anything you want. And thats before we talk about emulators and other side piece of software that is 100% open source.
Epic is a propriety gaming company that is locking stuff to there store origin was the same but unlike origin Epic is selling your info out to the Chinese communist party. Epic's store is unusable, the rootkits hidden in there store front raise legality eye brows and the fact that they just steal exclusive deals and lock them on a store front behind other shady practice is disgusting.
MS,Sony,Nintendo,Steam,GOG arent like epic in the slighest even Origin and Uplay aren't like that the fact that Epic is backed up by the CCP and Tencent is reason alone not to touch that store with a 10ft pole.
