I disagree. The Core Rules should be the vanilla ice cream. The campaign settings provide the toppings (nuts, as in FRs case) to add the flavor.TwoSix said:The first released campaign setting should be as vanilla as possible, in order to introduce people to the new setting elements. Making a setting that breaks all the rules doesn't mean much if people don't know the rules to begin with. FR 4e will be the vanilla, Eberron 4e will be the chocolate chip cookie dough.
