Hello!

GOG always scans may computer and shows the games I got in Steam or other plattforms. I don't like that. I am not able to find my GOG Games when it does that. I tried to change the options, but I just can connect to steam - I can't find how to remove the steam games.

Can anybody tell me how to do so?

Best greetings

Finding GOG games in Galaxy is very easy.
There should be premade 'GOG.com' bookmark on the left. Clicking on it will display all your GOG game.
If the 'GOG.com' bookmark is missing you can restore it by using Galaxy filter.
Go to 'Owned games', click on 'Filter' button at the top and select 'GOG.com' from the 'Platform' menu.
After that you can click the ribbon icon at the top left to add a bookmark with the selected filter (GOG games).

If you want to remove all Steam games from Galaxy you need to connect the integration to Steam and then click on Disconnect.
(this is how it works at the moment)

Thanks! I will try that.
