| 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. | Roll d20 + modifier against a target DC (for ability checks and saving throws) or AC (for attacks). Meeting or exceeding the target succeeds. Advantage rolls 2d20 and takes the higher; disadvantage takes the lower, replacing most situational modifiers. |

| Best For | Groups wanting the classic AD&D feel with streamlined, unified mechanics — old-school spirit with modern ease of play. | Groups who want heroic fantasy adventures with tactical grid combat, deep character customization, and access to more published adventures and supplements than any other RPG. |
| 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 | Advantage/disadvantage system simplifies most situational modifiers to a single mechanic. Extensive class and subclass options across 12 base classes with 48 subclasses in the 2024 PHB. The largest third-party content ecosystem in tabletop RPGs. Free basic rules and starter sets lower the barrier to entry. |
| Considerations | Primary/secondary attribute split can feel arbitrary, limited non-fantasy support | High-level play (tier 3-4) introduces significant spell interaction complexity and encounter balancing challenges for GMs. No official rules for non-fantasy genres. Three core books at $50 each represent a significant investment for the full rules. |
