I tried that some time ago, and at least at that point it needed configuration to get up and running. It was a hassle. I have family that needs a lot of my time at the moment. Between August and December I could find less than 10 days where I was able to decide by myself what I do after workdays or on weekends.
I'm not going to spend those precious minutes configuring any damn thing. Steam works out of the box. Now someone was just mentioning something called Heroic launcer. Sounds good. Wonder why Gog is not linking to it very visibly on its site if it works?
