I made the deliberate decision years ago not to play multiplayer games even though having almost exclusively played those. It was just to get away from all the toxicity and competetiveness.

So from then on I have only played singleplayer games, and it have been such a positive change for me. Much more entertaining and no stress at all. And the bonus was of course that it made switching to Linux gaming so much easier, since I didn't miss out on anything I wanted to play.
