Luddite said:The "Sacred Cows" posted by John Tweet, when they designed 3rd Ed, are what defines a game to be DnD and not "Yet another fantasy game." Personaly, I agree, the sacred cows are what makes the game DnD. This does not mean these bovines should be used in d20, but they are essance of DnD.
This, of course ,raises the question: what do you consider the sacred cows? hp/ac? stat range? The Six Stats? particular classes? What about magic is sacred for you? The particular spells? Just the schools? The divine/arcane distinction?
