Yes, it appears to be a similar reason why you cannot import Xbox app games into Steam, nor can import Epic Games intro steam as steam games, works as non-steam games but I haven’t tested that much yet under linux, I have did the non-steam epic games under steam in windows before that works, but linux might be work or not for some of the titles, which do work under Lutris. I like Lutris, but I haven’t fully tested it yet to see all my games work under it. I plan to use GOG Galaxy for it or GOG app on Flathub, going to try that app too, in time.
I reason to keep my newer desktop on windows is for the xbox app games, like fallout 76 game from windows that was free with amazon prime gaming, but it’s locked into the Xbox app, as I do not think you can play it from steam or at least not the free access version.
I also like the life is strange series, for example the remaster versions are ok, but the newest title they released has some sort of DRM in it, but I only got the disc for my console, so it may show up under Xbox app but its not playable from there as I don’t own that one digital, now the true colors life is strange game I do own digitally and got the remastered collection free with that pre order of that game, but for whatever reason the remastered collection was not cross compatible only the main true colors was in that release.
as for why I am doing the Bing points for redeeming stuff I guess I could go into google chrome or Firefox and do points that way too, but anyway I am working on unlocking lord of the rings movies, and the hobbit ones, since they have a good deal for them like 1500 points for each movie, which unlocks the 4k movies anywhere versions which I can watch on my oled 4k tv set at home, but yes it sucks that it takes so much time to unlock them doing daily searches, also mobile searches gives me 0 points of the 100 points since they don’t count android tablets 10.1 devices as mobile hardware, since when I use Bing app on my android tablet its giving me pc 150 points instead it’s been that way for a long time now. I am not sure about playing bazzite steam deck games on a oled tv set if that would work, or if its a good idea, I heard some older oled tv’s had some problems with oled but since its a newer model, I don’t think its affect by the same ghosting problems, like logo and stuff were once bad for oled based tv sets. tv set is lg oled 4k c4 model of tv which I use for my series x console and ps4 at home, and smart apps for watching movies on it too.
which is why I do need to keep my newer pc on windows 11, the cross platform game access with my series x is about the only reason to keep using windows 11, as I don’t care for the phone access apps that windows 11 now comes with, as I don’t own any android phones just my android tablet which is a wifi device only.
other apps in xbox app that are some of them cross platform games.
