Indispensable Game Books

Sorry I haven't posted much lately. I've been doing a lot of reading, and busy at work, and at home; I actually have a long-ish post that I've been working on for a bit.

In lieu of a more substantial post, I thought it'd be interesting to note the books that I try to have on hand when I am preparing and running games.

• B2 Keep on the Borderlands. The PCs use the Keep as a home base.
• Ready Ref Sheets. This should go without saying.
• Holmes Basic D&D Rulebook (1st edition, 3rd printing). In case I want to reference any rules or spells left out of Moldvay.
• The First Fantasy Campaign (1st printing). In case I want to reference any rules; the Blackmoor Dungeon is my fallback if I have absolutely nothing else to run.
• Metamorphosis Alpha (Print on Demand reprint). For mutations and science-fantasy goodness.
• Empire of the Petal Throne (Different Worlds reprint). In case I want to use Tékumel rules, monsters, or items.
• Mythmere's Adventure Design Deskbook, Volume II - Monsters. Obvious.
• The Random Esoteric Creature Generator. Same.
• Moldvay Basic D&D Rulebook. I'm running B/X, so it makes sense.
• Cook/Marsh Expert D&D Rulebook. As Moldvay above.
• The Dungeon Alphabet (non-expanded edition). For the charts.
• Dungeon Masters Guide (1st edition, 2013 reprint). For the charts.

Since I play D&D mostly via Google Plus these days, there's also a copy of OD&D within arm's reach as well, and one of the Dungeon Crawl Classics RPG. But they're generally not in my prep list, and I would very rarely consult them during a game.
