I've found that GOG generally has around 40% of the games I like on Steam, so I use lists like this to find interesting ones and then check GOG if it's there so I can avoid paying Americans anything.
It doesn't always work. Steam's library is huge, but I'm doing my part for the whole #ElbowsUp thing, and for me, that means sending as little money their way as possible.
...and honestly, targeted sales like this make me think the boycott is properly hurting them.
Me too! I've been using Steam on Linux for a while, but thanks to American fuckery, I've had to experiment with leveraging Proton in Heroic to play GOG games. It's pretty smooth though. I installed Disco Elysium this morning and it Just Worked™. I then went ahead and bought a bunch of indie games: Dorfromantik, Frostpunk, and Terraformers in GOG's own Sumner sale. Not Canadian games mind you, but also not American ;-)
It's pretty good, but my problem is that if a game doesn't run I assume it's because I screwed something up. For example, Synergy, has a platinum rating and it installs just fine, but once started is just do slow for even drawing the starting menu while my CPU goes crazy. Clearly there's a problem with it not using my GPU, but fucked if I know what package I didn't install/configure properly.
