Yeah I respect that dedication, I tend to buy on GoG and itch but as a Linux gamer I sadly find Steam much more conveniant, less tinkering to get my games running than using Heroic or Lutris. I do support DRM free and that's why I sometimes buy games on GoG that I already "own" on Steam even if I don't plan on playing them in the near future. However the sad reality is that most publishers treat GoG users as second class citizens and many updates, languages or DLC never make their way to GoG:
