From the introduction: This is a trimmed-down, subminiature version [of Microlite20 Comprehensive Edition] that has been designed to be quick and easy to play. The goal was to create a simpler game, but one where all the resources (monsters, spells, adventures and equipment) could be used without conversion. This Microlite20 Comprehensive Edition Player's Guide includes just the rules and lists (equipment and spell) that a player needs to create and play a character.
