My partner loves these. Those he watches have some form of appealing commentary that adds to the experience. For certain games like "Among Us", it can be very funny.

I don't watch because I don't often have energy but I liked watching with him when I was visiting.

There are many video games I don't own or don't have the ability to play or have a group to play with. I can barely manage Fallout Pen and Paper with my friends because they love multi hour sessions and I get way too tired.

Partner also loves Critical Role, a Dungeons & Dragons show with professional voice actors. I however don't have the stamina to watch long videos, however entertaining.
