While I don’t listen to any “narrative play” podcasts (as I’ve heard them labelled as) I do listen to an amount of improv based podcasts. So on some level I understand the appeal. Also if you like comic books or blaseball or anything lore-heavy, that would be adjacent to narrative play.
Let’s plays are speedrun adjacent so I also kinda like them. That being said that’s just what I get out of them. Everything I enjoy I have in mind that it ain’t for everyone (boy I wish it were for more people though…)
