Microlite81 Advanced Expanded (Tablet/Digest Edition)

A rules-light fantasy roleplaying system inspired by early Basic and Expert fantasy games, with classes, spells, and treasure from advanced editions. Players create characters by rolling four attributes and choosing a class, background, and alignment, then explore adventures, manage combat, and develop strongholds and dominions. Standard and extended rules support different levels of complexity, with optional mechanics for advantages, morale, hirelings, magic research, psionics, and more. The digest-sized collection includes expanded monsters, magic items, spells, random tables, guidance for small parties, a sample campaign, adventures, and dungeon-creation advice. Its rules are compatible with many B/X, BECMI, and first-edition fantasy adventures.
