Proton is a remarkable accomplishment; I never believed it would have worked as well as it does. It helps that newer games are increasingly based on a couple of engines (Unity in particular) but its support for older games is also impressive. Proton is the basis of Chromebook's experimental Steam games support. It works pretty well, as well as Proton itself as far as I can tell.
