Gaming on Linux is pretty damn great nowadays. More and more new releases run day one, Proton and Wine are being tirelessly worked on, and for most games it's as simple as enabling Steam Play in an absolutely seamless set-and-forget type of way.

The biggest problem are still competitive games and their anticheat, and while some titles enable Linux support, others go out of their way to show us the middle finger, sometimes even banning accounts using Linux.
And that only gets worse when so many games have moved to more invasive anticheat solutions that wouldn't work the way Linux handles these things.
