agreed with hootaloo, it's pretty inane to complain about video games and let's plays running for too long. also it sounds like you have never even listened to metal.
I dunno, let me try to explain it better. A 150 part YouTube series is too long to watch. I don't have the time to do it, and even if I did there's better content out there for me to watch than that. I don't understand why people like it, hence my posting it in this thread. I'm not trying to complain that it exists, because that'd be dumb, I'm saying I don't know what the appeal is.
And my gripe isn't with metal as a genre. There's plenty of metal there that's perfectly fine and that I enjoy. Maybe I wasn't specific enough about what particular genres of metal I didn't get.
I also don't know where you're getting "video games running for too long" from. Is that a typo?
