I’m into TTRPGs and in particular play-by-post, which is usually done asynchronously, because you can play a much bigger role in the storytelling element of the game. It makes you, the player, a part of the exchange again. That’s the point of games. In games, you make choices. You shape the outcome. In movies and books you typically do not, the main exception being CYOA, which feels like a cheap knockoff of TTRPGs, which are semi-freeform.
