Advantage rolls 2d20 and takes the higher; disadvantage takes the lower, replacing most situational modifiers. | Roll d20 + modifiers vs. target numbers (THAC0/AC for combat, saving throws for hazards). Ability scores rolled on 3d6, class and level determine hit dice, spells, and abilities. GM acts as referee for rulings. |

| Best For | 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. | Players who want the classic AD&D 1e experience with cleaner organization, well-defined rules for combat and spells, and a huge library of compatible OSR content. |
| Highlights | 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. | Faithful AD&D 1e rules reorganized for clarity, large back-catalog of compatible adventures, middle-ground complexity between B/X and modern D&D, active OSR community, free PDF available |
| Considerations | 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. | Deliberately old-school — THAC0 and descending AC may confuse modern players, less balanced than modern systems, relies heavily on GM rulings, limited character customization compared to newer games |
