Expectations
Stonetop works best with 3-5 people: the GM and 2-4 players. With just one player, some of the mechanics and procedures fall flat. With 5 or more players, it becomes increasingly hard to share the spotlight, make decisions, and keep things coherent.
It's best if the players are consistent from session to session. Players have a lot of input into the fictional world, and they decide together how to deploy their village's resources and what projects to pursue. When you have different players each session, it's hard to keep everyone on the same page.
