you might surprise yourself if you fly by the seat of your pants, if your problem is story related why not start with the simple rat celler style campain for session zero something fast and easy and requires little plot, if your problem is getting folks to show or just finding them up why not use the internet and make a discord/teamspeak and roll20/tabletop sim and put a link up here sticky optional for when dnd/ table top is and let it grow from there, if writing itself is your weakpoint... well i cant give many sugestions there maybe watch terable writing advice on youtube and read the fics on the ppc wiki for examples of what not to do and what to do?
