I happened to come across a copy of the 5e DMG today at work. While I did not get a chance to look too closely at it, a I was pleasantly surprised by all the random tables of dungeon dressing and even random traps and tricks. The other thing I was drawn to was the ‘further reading’ — in this case “Appendix D.”
It’s a fairly interesting list, mixing both some old chestnuts (Gygax’s Role playing mastery makes an appearance, as do several old TSR sourcebooks and even Grimtooth’s traps) as well as some kind of odd choices (as large number of histories of D&D, from Peterson’s epic Playing at the world to the rather underwhelming Of dice & men), a few reference books (including the Writer’s Digest fantasy writer’s reference book, which I happened to pick up at a used book sale recently and thought was a good introduction to the tropes of pseudo-medieval worlds, as well as suggesting some ways to break free of them).
The only thing I found odd was the large number of books on writing, and not just the world-building part but writing drama. That bugs me a little, since I never really liked the “DM as author” idea. The players should be creating the drama too; it may in fact be more their job than the DM’s job. The DM just gives the players levers to pull and things to interact with; the player’s horrible choices and heroic deeds can create all the drama you need. But I probably shouldn’t read too much into that.
But I am pretty happy to see that the PHB and the DMG both have reading lists. I still haven’t had a chance to look at a Monster Manual so I don’t know if that has a reading list too. I hope it does.
