Surely not a rare opinion, but Undertale. Especially if you do a fully blind playthrough, since you get to see the consequences of your actions:

!Characters disappear from the overworld, other characters mention they're missing... and you can get a very shitty ending, like I did, where Undyne takes over the kingdom and exiles Toriel because I was an irredeemable murderer in her eyes.!<

It depends on the focus: if it's on showing how to progress through a specific part or on highly technical gameplay (like a speedrun or a hack), then, sure.

But, if the video is just playing the game normally, I'd rather get some commentary; if not, why would I watch it instead of playing myself? I'd prefer to feel like I'm watching with someone. That's why 95% of my videogame-related watches have been with commentary.
