Retro RPG: Hackmaster: Players Handbook and Games Masters Guide
HackMaster is a fantasy role-playing game produced by Kenzer & Company. It began as a fictional game, a parody of Dungeons & Dragons played by the characters of the Knights of the Dinner Table comic strip by Jolly R. Blackburn. The characters in the comic began playing fictional HackMaster 3rd Edition, which was updated and published in 2001 as a numerously revised 4th edition. It has been hinted the name of the game was originally changed for copyright reasons.
The current 5th edition has removed most of the parody aspects, and contains game mechanics written from scratch in order to avoid any intellectual property problems.
