No.I am not sure if this has been discussed but I wonder if the time has come to move away from the term Dungeon Master to describe the role of the person who runs the game. Is this term appropriate or anachronistic? Has the time come to refer to this role as the Game Master, Referee or something else? I am not sure. What do you think?
No.
In Dungeons & Dragons, the official title is Dungeon Master (which is also a trademark).
It is wholly appropriate.
Why would you even ask this question?
