MerricB said:The results of that survey were important in the design of 3E, from what I understand. In particular:
* An average D&D campaign lasts about 1 year.
* An average D&D campaign has 1 DM and 4 Players.
Also note that while they state an average, they don't state the standard deviation. We don't know the width of the peak. Perhaps they are tightly bunched, perhaps not. The "average" may represent a great many 2+ year campaigns balanced by many 2 month campaigns.
