This is to be expected and don’t let it turn you off using Galaxy. Once set up you can automatically launch (and close) the game and client from here without seeing the other apps.
It does work with Steam, Ubisoft etc but the login will expire every week and need reconnecting.
GOG Galaxy let’s you combine most of your game library in to one but it has it’s issues. GOG, Epic and Microsoft Store all work great but the other clients aren’t officially supported.
F1 Manager 2023, my interest in the real sport has completely disappeared over the last few years but I like management games and it’s doing a decent job.
Jusant, recently added to gamepass and so far I’m really enjoying everything about it. The gameplay, art style, lore and mystery are all excellent.
Titanfall 2, decided to replay the campaign but the spider bomb machine things trigger my phobia so taking a break with the games mentioned above. Such an amazing game even with my issues!
Yeah it’s been great building up a GWG library, especially the 360 games, but you’re right that most of the time it’s been underwhelming. For me this change is good.
