How much detail to create before the session versus during the session?
Two versions of a map of a road through the woods below. The first has boulders in open grass and stream areas. The second has boulders and significant tree trunks throughout the wooded area.
However, the GM could add details, even the boulders in the open areas, during the session as new sections become visible: “You peer deeper in the woods and see a couple massive trees with a few boulders . You hear muttering from behind this boulder .”
What’s the better approach?
