I am a bit old, and never got why so many people watch “actual play”. I’ve done it once or twice to get the mechanic of a game, but found the experience more technical/boring than fun.
I get having a guest or candidate player watching an in person to see how rpg work, or whether they click with the group, but somehow watching video of strangers playing RPG doesn’t sounds fun to me. But I might miss something considering how popular these actual plays are
I don’t like most of them, but I enjoy Dimension 20 for the creative homebrew settings and funny group dynamics as well as the editing.
I also will occasionally watch an episode of a different actual play if it uses a system I’d like to try out, for instance I was thinking about running Beam Saber for some friends, so I found a one-shot actual play where the GM was the creator of the game. That gave me a strong idea of the intended style of the system and tone of the setting.
