Core MechanicRoll d20 + attack bonus against descending Armour Class to hit in combat. Saving throws are roll-over by category (Breath, Death, Stone, Wand, Spell). Initiative is d6 per side each round. The GM (Maze Controller) tracks time, light, encounters, and resources — torches burn out, rations deplete, and random encounters escalate with noise and delay.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 ForOSR veterans who want a traditional dungeon-crawling experience with descending AC, strict resource management, and classic class-and-level gameplay — especially fans of Barrowmaze and megadungeon 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.
HighlightsComprehensive old-school toolkit with 11 classes and 8 races, heavy emphasis on dungeon exploration procedures (marching order, light, time), critical hit/miss tables add combat drama, designed by a megadungeon expert, extensive spell lists and equipmentAdvantage/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.
ConsiderationsDescending AC and THAC0-adjacent math will alienate modern players, very large rulebook for an OSR game, tightly bound to classic dungeon fantasy, limited innovation beyond curating and polishing older mechanicsHigh-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.
