I used to think this way. Until I found that with emacs you can edit any file on an SSH enabled computer remotely. Meaning that not only are you no longer constrained by what the computer has installed. But you can use your personality configured editor while editing that file. It’s called tramp.
BTW, with Emacs you can use vim key bindings evil-mode, so don’t stress about that.

While I agree that proton on its own doesn’t make gaming on Linux a “first class experience”, it does sometimes perform better than the original native “first class” Windows OS that the game was originally intended to be played on. Which is just funny, but also shows all the work that has gone into proton.
Game devs need more Linux players before they make major industry wide changes, but proton makes those numbers have a chance of increasing by making the games playable on Linux.
Another reason why I wouldn’t call gaming on Linux a “first class experience” yet is controller and input driver issues. Which can be worked around like if I open a game I bought on gog through steam and use the steam input methods but I shouldn’t have to use steam to play a gog game with a controller.
I’m talking about not needing anything installed on the server though. Like you don’t need sudo. If the server has ssh then you can use Emacs to edit a file on it
