I recently got a haircut. I mention this to explain how I heard the phrase "A
barber is only as good as his last haircut". My barber elaborated by asking
"Well if I butchered your hair today would you come back?" It was a good point.
Con games are like going to a new barber. You don't know what your going to get
until you sit down. Some Cons have better reputations for games than others.
The same is true of Writers and GMs. However you still don't know what your
going to get until your in that chair.
I don't care what system we use to organise Con games. I care about the quality
of the games that are being run and that refers to both the game and the GM. I
see this as an issue that the RPG coordinator must address for their Con. How
he does it is irrelevant if it produces the best result for the Con's
attendees.
