It's a bit painful hearing all of the success stories on this page. I ran into endless bugs running games under Wine, eventually gave up and bought a vanilla PC just to run Windows for games, and that still gives me endless bugs with most major games, but somewhat less than Linux does. With my level of hardware fu I should stick to consoles, but mods make games accessible to me.
That you say "running games under Wine" is a hint it was a while ago, the modern way to do this is to install Steam and let it handle the compatibility layer.
Similar anecdote, in the past week there have been two separate games that I wanted to try out, and both were nonfunctional on linux. One had a completely black screen, and the other ignored all mouse/keyboard input. For each of them I spent 15 minutes tinkering with winecfg, installing packages, googling error messages, etc. Eventually I gave up and booted back into windows where they worked perfectly.
Keep posting. Comments like yours bring balance to the linux ideologue that everything's all fine and dandy. We need some truth in this.
The last thing we should want is to have an innocent, how-to-pay-rent-on-his-mind, game dev develop for linux thinking it's good only to find out there's a ton more bugs to solve (and having no help for solving them) for 0.01% of his customer base.
I have a collection in my Steam library labelled 'Broken', where I group games which didn't run when I tried them. So far it contains 6 games of the 656 I own.
My mother uses Windows 11 and it's absolute misery. I had the eID stuff working under Firefox, then one day it just stopped working. After a lot of flailing about I couldn't get it working again and I eventually caved and installed Chrome. Then it worked for a few months and it stopped working again. Now I have her use Edge for eID stuff, but if that fails I'm just gonna get her a System 76 laptop with Linux Mint because it Just Works.
A random assemblage of parts running Ubuntu, upon which most things that weren't Windows games ran fairly reliably for a decade plus. As far as I can tell nothing challenges a computer like games, except games from an alien OS.
