Depends on the game. There's some horror games I wouldn't bother with because they're just too much for me, but I find it funny as hell to watch other people play and get scared by them. Then there's group games like Among Us. I hate playing it, but it's great watching other people get salty over it.
If you're the kind of person who likes to be surrounded by drama, I guess it's great, but I have to deal with drama and liars on a constant daily basis with work on top.
However, one of the funniest things I've seen was watching Vinny playing with randos and terrorizing kids.
