@gamingonlinux I'm pretty certain game launchers are there to force people to stop playing games for a bit, when they inevitably get updated and stop working for a day or two, until Proton Experimental catches up.
It's the PC equivalent to Nintendo's old "why not take a break?" screens, but on a different timescale.
Most of the time, it's: "Stop playing Assassin's Creed and visit the real world." (It's usually Ubisoft breaking their launchers weekly, right?)
