Hey! !pbta@ttrpg.network would be happy to discuss this!
But in general, building whole campaigns isn’t a thing PbtA games do, and instead they use the fact that the game engine forces the narrative to keep moving and constantly provokes the players to react and take action to drive the game onwards.
Have you played / MC’d any other pbta games?
Hey, I’m a mod over at !pbta@ttrpg.network and it’s great to lurk around and find out where the various ttrpg communities are springing up.
