I mean, the thing that people watch twitch for is mainly the person/people on the stream, the game is a backdrop, rarely the actual focus

And not everyone is ego-centric like you’re saying? I mean, there’s literally tens of thousands of streamers. Don’t just look at the biggest ones that probably mainly appeal to kids, i.e. a different audience than you. Chances are the kind of people you would enjoy watching are just smaller and more niche
