While I agree with you on the fact that it's way easier to run games on Linux than ever (especially steam games thanks to proton and DXVK, but it trickled down to most games as well) and that Linux never had so many supported games, I still spent 3 hours to install torchligh 2 the last time I wanted to play with it, dispite it being sold as Linux-compatible! Oh, and I spent 4 days (not full time obviously) installing WoW Classic last year, and it involved manually installing a release-candidate of the latest kernel. So it's still definitely not for the faint of heart.

But at least now it works! (Unless it doesn't because some retarded anti-cheat software which doesn't actually prevents cheating, gets me banned after a few minutes. Looking at you Apex Legends)
