“Dave [Arneson] and I disagree on how to handle any number of things, and both of our campaigns differ from the “rules” found in DandD. If the time ever comes when all aspects of fantasy are covered and the vast majority of its players agree on how the game should be played, DandD will have become staid and boring indeed. Sorry, but I don’t believe that there is anything desirable in having various campaigns playing similarly to one another. DandD is supposed to offer a challenge to the imagination and to do so in many ways. Perhaps the most important is in regard to what the probabilities of a given situation are. If players know what all of the monster parameters are, what can be expected in a given situation, exactly what will happen to them if they perform thus and so, most of the charm of the game is gone. Frankly, the reason I enjoy playing in Dave Arneson’s campaign is that I do not know his treatments of monsters and suchlike, so I must keep thinking and reasoning in order to “survive”. Now, for example, if I made a proclamation from on high which suited Mr. Johnstone, it would certainly be quite unacceptable to hundreds or even thousands of other players. My answer is, and has always been, if you don’t like the way I do it, change the bloody rules to suit yourself and your players. DandD enthusiasts are far too individualistic and imaginative a bunch to be in agreement, and I certainly refuse to play god for them — except as a referee in my own campaign where they jolly well better toe the mark.” — Ernest Gary Gygax, Alarums and Excursions #2 (July 1975)
