Microlite78 First Edition Lite (Condensed Type Edition)

A rules-light fantasy roleplaying game that adapts the style and feel of 1978-era first-edition play to a streamlined d20-based system. It includes detailed character classes, an old-school experience system, monsters, spells, treasure, strongholds, magic research, optional psionics, and other core rules. The compact rules support traditional dungeon adventures and are compatible with original first-edition material, as well as BECMI, second-edition, and modern OSR adventures with some adjustment. The game assumes the referee has a basic understanding of roleplaying games and d20 mechanics.
