Core MechanicSIEGE 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.Roll d20 + modifier against a DC. Four degrees of success: critical success (beat DC by 10+), success, failure, and critical failure (miss by 10+). Each turn grants three actions to spend freely on strikes, movement, spellcasting, or other activities. Multi-attack penalty (-5/-10) discourages repeated strikes and encourages tactical variety.

Best ForGroups wanting the classic AD&D feel with streamlined, unified mechanics — old-school spirit with modern ease of play.Groups who want deep character customization, tactical grid combat with meaningful turn-by-turn decisions, and a richly detailed fantasy setting with free rules.
HighlightsSIEGE Engine unifies all attribute checks, easy to convert AD&D/d20 content, 13 classes with classic archetypes, fast character creation, large back-catalog of adventuresComplete rules available free on Archives of Nethys. Three-action economy gives every turn meaningful tactical decisions. Character customization through ancestry feats, class feats, skill feats, and general feats at every level. Four degrees of success on every roll add granularity to outcomes.
ConsiderationsPrimary/secondary attribute split can feel arbitrary, limited non-fantasy supportNew players must learn the trait system, conditions, and four degrees of success before combat runs smoothly. Multi-attack penalty and numerous combat actions can slow turns for indecisive players. Character creation requires selecting feats from multiple categories at every level, which can overwhelm new players.
