Of all the things that I never imagined I would end up working on, I was asked to help put together the Trivial Pursuit D&D edition, which has just been released. It is, well, Trivial Pursuit, but with D&D-specific questions: on monsters, spells, campaigns, characters, and of course the game's fifty-year history. If that sounds like something you'd be interested in, you can find it at the usual places online and in person -- my FLGS just got it in this weekend.
David M. Fitzgerald's E'a: Chronicles of a Dying World is one of the more obscure digest-sized unofficial supplements to early D&D, little known even in the community of its day. E'a did warrant a blurb in Heroic Worlds (1991), and now even has an RPGGeek entry, so it cannot be considered entirely forgotten, but very few were printed. As with many small-press items of this era, trusting the 1979 copyright date inside the book is risky at best -- but through equally-obscure catalogs, it is possible to establish roughly when it became available.
As another anniversary of the birth of Dungeons & Dragons passes, let's look back 48 years to the heady days of 1974, when the idea of dungeon adventuring had only just started to capture the imagination of gamers at large. Alistair MacIntyre had long run "Operation Contact" for the International Federation of Wargaming, so he knew everyone and viewed the release of D&D with some interest -- though he confessed, "I don't have the time or knowledge of fantasy to participate in your underground adventures." He was however "fascinated by the dungeon mazes," and came up with a number of devious dungeon layouts that he photocopied and shared directly with Gary Gygax and others that summer of 1974. Above you can see a dungeon entrance from the wilderness that MacIntyre proposed -- and at the bottom of the cut below, there's a little trick from Gary himself as well.
