I’ve watched some here and there, but having to try to catch them when they stream has put me too much in the mind of old tv and catching shows when they air. Watching the recording afterward is maybe good for some white noise, but it’s clearly not the intended experience I think.
You’ve perhaps compared the wrong niche though. Game streamers are the Harlem Globetrotters; you’re not there to watch excellent gaming, but entertaining gaming. Whereas esports are the equivalent to competitive sports.
That said; I too struggle to care about watching either. Even my old boss Limmy, no care for watching him stream.
