As a DM I'm often wondering if I'm presenting the dungeon to the players and even myself as best as I can.
I wonder to myself if by keeping to old tools we are keeping our campaign and adventures from developing beyond old boundaries. My imagination can picture vast dungeon environments that the classical graph paper method is just sorely lacking in properly recording. Maybe the computer has given us the means but the exact tool-set isn't here yet as compter and video games allow impressive spaces to be designed but the means these are explored by players are still significantly different from how tabletop play unfolds.
Are we visualizing our dungeons well, and are the other players really seeing what we think they are?
