Just to clarify in my mind is the game on the Aerodrome involving 3 separate mats (one for each player and one for the moderator)? Or is there just one map that the GM is using to monitor moves? If there's only one mat and the GM coordinates everything after the players submit moves this may not be too complicated to do if players agree that the final word on moves and combat is the GMs?

Bottom line is the GM mat and turns is all we'd see here, whether player or peanut gallery observer.
