Yeah, if I’m playing it (ie. stuck) or don’t really want to but want the story, I’ll watch 'em. I don’t watch commentary gameplay vids for the gameplay.

Depends on the game.

boring

Well it depends if the gamer playing the game has a good personality then commentary anyday but if otherwise then no commentary

Depends if I’m watching for hints/help or to be entertained.

I tend to prefer commentary because 90% of the time if I’m watching gaming videos it’s either twitch streams or speed runs, both of which are a lot more entertaining with commentary.
