At‑a‑glance: B/X lineage • d20 tests, ascending AC • 3–5 + GM • Low prep • Rules‑lite • 2–3h sessions

Theme and Setting

Classic dungeon‑fantasy with a toolkit ethos. The core book folds PCs, GM tools, and a bestiary into one volume, letting you run gritty delves, wilderness treks, and city capers without lore lock‑in. Tone skews pragmatic, lethal when you overreach, and friendly to published modules.

Core Mechanics and Rules

Roll a d20 for saves and checks; armor uses ascending AC for quick target numbers. Races and classes are distinct, echoing B/X while modernizing some edges. Equipment and encumbrance keep risk palpable; combat is brief and decisive; magic is potent but bounded. Procedures favor clear fictional positioning and fast adjudication over exception lists.

What Makes It Unique

A thriving open‑source ecosystem: hundreds of free supplements, adventures, and optional modules expand the core without bloating it. The single‑volume format keeps cognitive load low, and compatibility with classic adventures means you can run decades of content with minimal conversion.

Target Audience and Player Experience

Great for new tables and veterans who want OSR tempo without heavy crunch. Expect quick chargen, meaningful logistics, and rulings‑first play. If you crave deep feat trees and tactical subsystems, this stays intentionally lean; if you want speed, danger, and exploration, it sings.

Cairn

Cairn and BFRPG share OSR roots and fast, lethal exploration. Cairn pushes inventory‑as‑identity and procedural turns harder; BFRPG sticks closer to B/X feel with race/class and ascending AC—pick Cairn for tighter procedures, BFRPG for classic flexibility.

Knave

Knave is classless with slot‑inventory and unified d20 targets; BFRPG keeps race/class and a more traditional chassis. Knave excels at ultra‑light sandboxes; BFRPG offers familiar B/X structure and a vast community library.

Into the Odd

Into the Odd strips further—no attack rolls, brutal saves, Arcana‑driven weirdness. BFRPG is the broader B/X toolkit. Choose ItO for razor‑lean, industrial‑weird delves; choose BFRPG for classic fantasy with modernized targets and huge module support.
