I used to be a huge fan of GOG with the whole DRM free thing. But their poor Linux support just drove me to Steam. They promised a Linux version of their launcher for years. The request has 14,000 up votes. But they still won't create a Linux version. I honestly don't particularly care about the launcher, it's just the fact that Linux is not a priority for them.
Combining that with the lack of GeForce Now support I've basically gone to only using them for older classic games.
