When I start I have a session zero with my expectations. If you cross those, I just drop you from the table. I don’t have murder hobos because I don’t let them murder. If they try I let them go. Only takes one to test that and then your game plays smooth. They know how I want to play and if they aren’t happy with it, they can run their own game.
This will be adventure modules and other official content to be purchased. Hopefully with all the bells and whistles you can have in Foundry.
Not sure if there is a big market, as most foundry users are comfortable putting the scenes together already.
