Core Mechanic
SIEGE Engine: roll d20 + modifier + level vs. Challenge Class (12 for primary attributes, 18 for secondary). Primary/secondary attribute distinction replaces complex skill lists with a single unified check system.
Best For
Groups wanting the classic AD&D feel with streamlined, unified mechanics — old-school spirit with modern ease of play.
Highlights
SIEGE Engine unifies all attribute checks, easy to convert AD&D/d20 content, 13 classes with classic archetypes, fast character creation, large back-catalog of adventures
Considerations
Primary/secondary attribute split can feel arbitrary, limited non-fantasy support
