Just a high level comment on GOG, I am immensely grateful to them for existing and for sticking so strong to their principles against DRM, and for maintaining great customer service. I have bought a lot of games from GOG and have been very happy. As an exclusively Linux user, I also appreciate how well GOG works with Lutris et al and that they aren't making life harder for those devs. I
love the offline installers and I deeply appreciate their availability.
I'm not a big gamer but after watching the industry and Linux/open source in general for many, many years, I'm more convinced than ever that it's the gaming community who will save general purpose computing (that's also a nod to Valve for everything they've done for Linux as well, which has been major).
