No knocking it for those that enjoy doing so but I’ve personally always found the concept of watching others play a video game — bizarre.
There’s a few exceptions though - I’ll watch someone if my purpose is to learn how they “do that” - ie a video to get past a boss for example.
The second exception if someone I know (a nephew, a friend, etc) wants to show me something.
Beyond that though just burning my precious game time to watch strangers play - I can’t do it.
