I am replaying it with my partner. She doesn’t want to play, but she wants to see the visuals and the story. She makes all the decisions and I just control Jin. It has been interesting because her enjoyment is kind of divorced from the mechanics (other than choosing non-stealth whenever possible).
There are quite a few reasons. New to DnD or RPGs, want to just get into the game, want to experience the cool backstory for each origin character are a few I can think of off the top of my head.
