Yeah, I understand all that, but first of all I have 4 gaming systems, 3 of them boot straight to Steam big picture (Desktop plugged to my living room TV, Steam Deck and Steam Frame), while I could have my gaming laptop for something different it just makes it easier to use the same on all systems, plus I would miss on cloud saves which make it seamless to switch from one system to another.
But here's the thing, to run things in Lutris I have to set it up myself, and setting it up with GoG downloaded installers or pirated versions is essentially the same, so what exactly is GoG providing me that I can't get by pirating? Am I only paying them for the legality of it?
