I haven’t watched the video, but I suspect it aligns somewhat with my own experience. Online fps used to be my goto genre, but the competitiveness, toxicity and the widespread cheating made me realise that it stressed me out more than it entertained me. So I cut them off a couple of years ago in favour of single player games, often moddable single player games with good replayability like Kenshi or Stellaris (although I also like more linear games which just provides some good no frills entertainment).

It really has made a huge difference in how gaming functions for me. Much more relaxing and stress relieving, not to mention that I have more control over the amount I play, since I can always just save the game and turn it off without feeling I am missing out on something.
