Running an RPG Saturday for Eclipse Phase, but with a diverse crowd, trying to keep the horror/drugs/destruction part of Eclipse Phase reeled in. Unless the players want that.
The c-card is a way to signal offputting ideas in the storyline. Alternatively also can use the o-card to indicate interest in a sidepath.
Script change Is an idea I first heard of in Teens in Space. It allows players to take more control over the narrative, to perhaps skip over areas, revisit them in a different way, etc. I've been in situations where the choices of some characters upset other characters to the point of emotional diress, so we went back and reran the situation in a different way.
