A producer once told me I had to write a description of a forest. Not a particular forest, the CONCEPT of forest. I said "I'm not writing that. I don't know what kind of catastrophic failure happened in whatever meeting you were just in, but the player knows what a forest is."

my favorite parts of the 3.5 DMG were its extensive descriptions of walls, doors, and the materials from which they could be constructed.
