Whereas Wizards of the Coast overhauled the rules for 3rd edition "Dungeons & Dragons", Kenzer & Company took the opposite action by revising the "Advanced Dungeons & Dragons" First and Second Edition rules (including various supplements such as 1st Edition "Unearthed Arcana" and "Oriental Adventures" and the mid-1990s "Skills & Powers" supplements) into a more coherent system and adding an element of parody. In part of that ability to use AD&D rules, K&C was required to maintain a higher level of humor than in the "Knights of the Dinner Table" comic for products that are revised from previous AD&D material. Completely original works for "Hackmaster" are not subject to this restriction imposed by Wizards of the Coast.
