Honestly might be the other way around for me. I was mainly a multiplayer guy for the longest time but most franchises I was invested in quickly went down the drain and a lot of the newer battle-royal style shooters didn't appeal to me.
Started mainly playing older games that had been on my backlog for a while. And videos of the Steamdeck running them games started popping up.
So since I already hated Windows 10 from the start and I didn't need my PC to run the latest AAA multiplayer games anymore, seemed like a better time than ever to switch.
I still play some multiplayer with Battlefield 4 and Battlebit Remastered. (R.I.P Battlefield 1 and Ironsight on Linux though...)
I'm still a relative newcomer and switched fully in 2023 after having zero experience with Linux before that year.
I feel like I've only just gotten comfy with regular Linux and don't feel like reworking my setup around the quirks of an atomic distro.
And if you count the Steamdecks "SteamOS" then the only time I've remembered it isn't standard Arch is when it's "atomicness" is forcing me to do workarounds for something that I can easily do on my Arch based desktop.
But I'd give NixOS a try if their docs page didn't block my VPN when literally no other FOSS or Corpo site does...
