If you know anything about me at all, I have a passion for the history of tabletop roleplaying. One of the books that helped stoke my interest was the book Heroic Worlds, which I read when I was in middle school. That book was a high level overview of the roleplaying game books that were on the market at the time – like the tabletop RPG equivalent of all those Leonard Maltin books giving an overview, one-to-two sentence of a film’s plot, and a one-to-two sentence review combined with a score. Monsters, Aliens, and Holes in the Ground provides a more close in view, covering a selection of RPG books from each decade of RPG history to date, with more involved looks at the various games.
