Honestly, I can see that. I’ve just gotten used to Lutris over the years, even before Valve released Proton.
I mainly like Lutris as a tool to manage all of my games with easy ways to share common configuration steps between them. But I also see it going the way most Wine helpers went over the years. At first it works brilliantly for everyone. Then the pre-made configurations fail to work for edge cases or they fail when a game is updated. Eventually it’s easier to configure everything by hand and then you don’t need the tool anymore until the next one comes along.
But they started an initiative with Bottles, Heroic and other programs to make standardised configurations. Pair that up with Valve’s efforts in Proton and the overall rising popularity of Linux gaming and we might get better and better tools down the line until they aren’t needed anymore.
