THE CRPG BOOK, from the UK’s Bitmap Books, is the culmination of years of work by over a hundred contributors. It’s one of the most comprehensive histories of CRPGs ever written, and features in-depth review-style writeups of over 400 games, along with essays on the ancient history of role-playing games (going all the way back to the Prussian Empire), the early days of MUDs (multi-user dungeons, the earliest online games), the archaic but impressive PLATO computer system, and the importance of paper manuals and hand-drawn maps.
