Call me uninformed, but I actually have this article to thank for introducing me to Proton - I have switched to Linux a few months ago, had installed Steam and played a few native Linux games, but so far I was completely unaware that most Windows Steam games can actually run on Linux too. You can blame Steam's very conservative default setting for this - only games that they have tested and certified themselves are allowed to run by default, to try other games you have to select "Enable Steam Play for all other titles" in the Steam settings (a dialog I had never seen before). But now I can happily (re)play most of the games I have amassed in my library over the years (and partly never played) - on Linux!
