1974 Style is an homage to the World’s Oldest Fantasy RPG. The core rules clock in at a single, one-sided page, with an additional page of optional setting-specific rules to emulate Sci-Fi, Western, Horror and Pulp settings.
Another couple of pages of monster stats give a GM a minimalist bestiary to run a variety of adventures.
A typical old-school RPG module stats list for a monster looks like this: AC6, MV9’, HD 1, hp 4, #AT1, D1-10 by halberd. The 1974 Style rules use these same stats for player characters (PCs).
Character stats can fit on a 3×5″ or 4×6″ card, and all the rules for a given game and setting can fit on a single sheet of paper
