It should come right after year of the Linux.
Then we're doomed. I use linux (Fedora) as my daily drive, but I don't see it becoming more popular than Windows in the near future.
Gaming is the biggest thing that prevents me from switching entirely to Linux, unfortunately

It was my main concern, so I dualboot (my main drive 500gb SSD runs Fedora while I have another SSD of 1TB with Windows 10).

Most games I play are running flawless on fedora (rn I'm playing No Mans Sky), as most Steam Games (you can check protondb for your favorite titles) and I've been more than a month without booting windows, but other titles as Fortnite can't run on Linux.

For your games on Epic and GOG you can use Heroic Launcher. Gaming on Linux is getting easier on daily basis.

Two things are preventing me from switching to Linux

  • Gaming (specifically fucking anti-cheat -- which is arguably the biggest issue with getting games to run on linux)
  • Hardware that doesn't have native linux compatible software (sorry, not sorry, but I'm not looking to mess around with unofficial third-party software for my Elgato Stream deck and Elgato Wave 3 microphone. I want officially supported first-party software so I can have the hopeful convenience of it just working without having to fiddle around with it (which I undoubtedly would have to do with unofficial software)
  • Sometimes the open source software is better. I will always prefer cups and Piper to HP and Logitech software.
