The Ten Commandments of D&D

Issue #81 (September/October 1977) of Campaign magazine is notable for its lengthy overview/review of Dungeons & Dragons, written by Len Kanterman (of Starships & Spacemen fame) and Charles Elsden. The entire article is worthy of extended examination – and I plan to do just that over the course of several upcoming posts – but I thought a section toward the end might elicit some commentary. Dubbed the "ten commandments of D&D," they represent the authors' advice to traditional wargamers playing the game for the first time.

All told, it's not bad advice, though most of it consists of maxims long-time players have no doubt heard variations of for years. I'm immediately struck by two things. First, much of the advice concerns combat and the best way to survive it – no surprise, I suppose, given both the likely audience of Campaign and the nature of D&D gameplay. Second, the specter of the Killer DM looms large here or at least the idea that surviving a D&D session is difficult and it'll take ingenuity and the wise marshalling of a character's limited resources to achieve it.
