Being a role-playing-game dungeon master, you have to be familiar with how to absorb and implement the many, many game-playing books that are published to help you keep the adventure humming along towards epic goals. I have to admit to being a book addict. That is true for all books, but particularly game books. I collect them obsessively. I still troll Half Price Books looking for old and out-of-print D&D books and other game books.
Every role-playing game has certain necessary basic books. There is a book full of advice for the game master. It will tell you how to run an adventure and how to plan or map-out your events. There is a guide book for players that advises them on how to create a character, develop that character over time, and how to use the rules to create success. There is also usually some kind of enemies compendium, a monster book, filled with the characters you will have to defeat, slay, or outwit during the course of the adventure. Then there are game supplements that provide detailed settings, often complete with maps. They can give you non-player characters, adventure seeds, extra statistics, and sometimes additional useful tables. Equipment books are a thing as well.
I have a huge collection of Dungeons & Dragons books going back to TSR and continuing through their current publisher, Wizards of the Coast. I have practically every Call of Cthulhu book, a game system to turn H.P. Lovecraft’s horror fiction into RPG adventures. I have almost all of the Talislanta books, a D&D-like game with no elves, dwarves, or humans in their game. I have practically everything put out by Game Designers’ Workshop for Traveller. I have a few books from the Rifts RPG, a time-and-dimension bending science fiction game. I have practically all of the Star Wars RPG books. I have a lot of Star Trek books. I have some G.U.R.P.S. books (Generic Universal Role Playing System), some d20 RPG books, and many other odd books, including a boxed set of Rocky and Bullwinkle’s RPG, complete with hand puppets.
So, please don’t file paperwork on me with the authorities who put insane people in white jackets with extra long sleeves. I am a collector who suffers from hoarding disorder. And I love books. I just can’t help it.
