Reactive Freeform
In reply to ladysharlyne (msg # 5):
I guess I've had an embarrassing wealth in GMs throughout my gaming career, as almost all of the GMs I've played with since I graduated high school tended to run their games like that, even if they were system-based (if it was a prewritten module and we decided to go off the rails, they'd make something up, which may or may not have brought us back to the story but was never guaranteed to...)
Guess that would explain why I never heard the term before. To me, that 'reactive' style is just being a good GM, and we never needed to apply a further label to it...
But given the massive variety of players and playing styles out there, I can see where there would be a need to specify it.
