Back in the day, you weren’t really a referee if you didn’t use a screen of some sort to hide your maps, notes, and sometimes dice rolls from the players in your game. Consequently, I owned a lot of such screens, my favorite being the Dave Trampier-illustrated Dungeon Master’s Screen published by TSR. When I started up my Dwimmermount campaign in early 2009, despite my willingness to draw heavily upon my own gaming beginnings, I never once seriously considered using a referee’s screen. Part of it was simple practicality: referee’s screens traditionally take up a lot of space, space I didn’t have to spare at my dining room table, especially when I laid out the dungeon in Hirst Arts blocks. Another part of it was philosophical, for lack of a better word; my refereeing style these days is much more conversational, so a screen between me and the players would be an impediment rather than an aid.
