I'm going to run the Pathfinder's Beginners Box scripted adventure that has a dungeon map printed.
This is not only the first time GMing, it's my first time playing an RPG. All of the party are new to RPGs too,
To keep the layout of the dungeon hidden (to keep it mysterious and "unexplored"), I'm going to use crumpled tissue paper to cover rooms of the dungeons until they're explored acting like a fog of war.
If I explain to the players exactly what this tissue paper is for, and lift it as they move through the dungeon, could this have any unintended negative consequences?
