Is it possible to integrate in GOG Galaxy my Microsoft Store games??

The official Xbox integration should cover that. For Xbox Game Pass games the one caveat is that each game has to be launched at least once for it to be registered by Galaxy.

Thanks for the reply.

I connect Xbox and my game did not show on GOG Galaxy.

It looks like Galaxy integration for Microsoft Xbox/Store apps/games is pretty awful and totally broken at the moment. When I linked GOG Galaxy to my Win 10/Xbox account, all my games (Minecraft, Microsoft Mahjong and others) showed up ok. But only Minecraft is useable. Galaxy claims that all my other games are "uninstalled" and sends me to the Microsoft Store so I can "install" them! That's complete nonsense.

Why do companies release unfinished and broken software applications and expect the public to do their QA testing for them? GOG should have waited until Galaxy was in a professional, usable state before releasing it to the public. GOG, we are NOT your guinea pigs.

GOG Galaxy 2.0 is in Open BETA - that means it's functionally complete but requires testing and GOG have invivted people to help with that - it's not mandatory, there's no need to take part if you demand perfection in your free game launching software....

Using real people to test something like this works because everyone has WILDLY different collections of games across wildly differing platforms - it's near-impossible to simulate every situation.

Furthermore, the nature of integrating other platforms is that those things change constantly - I beleive MS recently changed how your XBOX/Windows Store games are displayed which has caused GOG Galaxy to not be able to access playtime for example - this will be an ongoing issue because that's how these things work.

There's a reason there isn't one really good game launcher - it's a really hard thing to do (trust me on this, I've created several!!)

I like how GOG have approached this but as I say, it's a hard thing to do and without people helping it won't work at-all

But...that's exactly what an open beta is for. Why do you take part in an open beta and then complain about the beta state of the software?

Tienes que añadirlo manualmente.

Ya, lo e conseguido pero los juegos solo se adicionan se se juega un poco.

Broh, its an open Beta dduh

it was open beta but now is force feed onto users in its busted state

You helped A LOT! thanks for the guidance

Just an update in case anyone is still having trouble making this work, my Microsoft Store games weren't showing up on the GOG Galaxy integration at first but if you run the game once and close it, and then Sync Integrations in GOG Galaxy, it showed up for me then. Seems they don't show up in GOG until they are run once through Microsoft Store / Xbox for some reason.
