They do. I use Linux exclusively recently and in the last year I played:

- The Forest
- Counter Strike
- Heavily modded Minecraft
- Arma 3
- Insurgency
- Insurgency: Sandstorm
- Squad
- Red Dead Redemption 2
- The Witcher 3
- Kerbal Space Program
- Papers, Please
- DOOM
- My Summer Car
- Portal 2
- Others I don't remember
The number of games that don't work on Linux is shrinking every day, DXVK and Wine are getting way too good. Take a look at proton DB for reference on compatibility [0]. You can input your Steam profile and it will show you how many of your games are playable and in what state. Currently in the Top 100 played games on Steam 78% of them are rated either Platinum or Gold. In the top 1000 that drops a bit to 75%, with only 3% of them being unplayable.
Oh yeah and all the games I've listed I played on Wayland (except the competitive shooters) :)
I play on my desktop and laptop and all my steam games run well, battle.net too. EA is the only that sucks. Cyberpunk, and other demanding titles. Really, not a single issue. I wanted to try linux as a desktop a few times but now itβs finally rather stable.
