However, there is also more text behind the Galaxy Client. This is why GOG can track your achievements, because Galaxy is made aware that you're playing it.

You'll notice that the destination of the shortcut doesn't point to the actual game, but to the GOG Galaxy Client. Now, Right-Click on the shortcut and select 'Properties'.

Important: You need the SHORTCUT, not the. To do this, you first need to find a shortcut to your game. In this case, you need to access Steam from the Steam Link, and from there launch the game through GOG Galaxy. Things get a little more tricky though, when you (like me) would still like GOG to recognize the game as opened, track your ingame time, achievements etc. The usual solution to this is adding the game as a foreign game to your steam library. However, at times you'll want to run a game external to steam (like on GOG). The Steam Link obviously only supports Steam games by default. Soo, this is just a quick tutorial about something I figured out and thought could be useful to some.
