Stuck in the DNS server.

apt install q-dns-client

Any recommendations?

They do provide Linux support in other ways though. They even troubleshoot me once with a game I tried to play on Linux and offered a refund.

Gog Galaxy not on Linux is a shame, yes, but its DRM-Free and Linux installers are enough for me to continue to buy from them.

Edit: Heroic Launcher makes a great replacement of Gog Galaxy, maybe even better than the Windows client, from what I’d tried. No multiplayer though.

It resembles the efforts of Archive.org and other culture-preservation driven websites/projects.

Internet is (or should be) our Library of Alexandria, where everyone is welcome —no matter their country, believes or financial situation— and have a feist on culture and knowledge like none other and for free. Games, art, books, cinema, Lemmy-like forums. You name it.
