It also helps that there have been very few important (big, complicated) applications in the past decade or two. Firefox is there? My development environment is there? I'm probably good.
But lutris as it stands now breaks everything almost every time I use it. I had steam unlaunchable for over a week because of something lutris was doing implicitly. Now running steam directly off the CLI seems to be working for 90% of the games I play (which isn't a very long list).
Only thing I doubt I will be able to figure out is stuff like fortnite or anything that uses easy-anti-cheat (since their devs give a fuck about linux and effectively believe we are all hackers trying to ruin their game).
That's all I got, don't bother with Lutris unless you have an insane amount of time to debug which component is missing.
