I definitely tried to make it so that you could play 2-3 sessions and have a pretty solid game in a short time, if only because I wanted to make it accessible to people who don't have the time for long campaigns, but I totally dreamed about people having long campaigns with Stand Up!! I'm really glad you're inspired to try! It's not against the main concept at all—Persona games are hundreds of hours long after all lol. I hope it goes well!
