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 adventuresThe three-action economy gives every turn the same three actions to spend on strikes, movement, or spells, so each turn is a fresh tactical decision. Characters customize through ancestry, class, skill, and general feats gained at nearly every level, letting builds diverge sharply within a single class. Four degrees of success, set by beating or missing the DC by 10, turn each roll into a range of outcomes rather than a binary result.
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 draws feats from ancestry, class, skill, and general pools at every level, making each build a slow step.
