What is Advanced Microlite20 OSS
Advanced Microlite20 OSS, like its parent game, Microlite20, is a trimmed down, sub-miniature version of the Primary Fantasy SRD rules that has been designed to be quick and easy to play. The goal of Advanced Microlite20 OSS, however, is to recreate the style and feel of the early editions of the world’s most popular fantasy roleplaying game published in the 1970s and early 1980s. Unlike Microlite74 and Microlite75 which replace most of the SRD with spells, monsters, etc. similar to those of 1970s editions of the world’s most popular fantasy roleplaying game, Advanced Microlite20 OSS is designed to provide old school style with modern 3.x style spells and monsters from the SRD. This provides a relatively rules light system that allows most 3.x adventures and settings to be played old school style with no more change that is required for standard Microlite20.
Advanced Microlite20 OSS is the equivalent of the Core and Expert Microlite20 rules. It makes the Microlite20 OSS system more “complete” at the cost of some additional complexity. Advanced Microlite20 OSS takes the basic rules of Microlite20 OSS adds material from the Microlite20 Expert set (new classes, etc.) and has somewhat expanded combat rules. It also adds the five Microlite20 skills back to the game, but in a old school manner. A simple talent system is provided for basic mechanical customization of characters. Metamagic, action points, and morale rules are also included. This almost doubles the length of the actual rules, from 2 pages to 3.5 pages. Advanced Microlite20 OSS also includes the notes on old school play included in Microlite20 OSS.
