Basic Fantasy RPG

Basic Fantasy RPG is a rules‑lite, B/X‑inspired fantasy game with ascending AC and race‑class separation. Classless-feeling flexibility and low prep make it easy to teach and run. Ideal for quick delves and sandbox campaigns where rulings and resource pressure matter more than build complexity.

At-a-glance

Fantasy • Needs GM • 3/5 complexity • One-shot friendly • Low prep

Basic Fantasy RPG

Tone skews pragmatic, lethal when you overreach, and friendly to published modules. Roll a d20 for saves and checks; armor uses ascending AC for quick target numbers.

Theme and Setting

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.

How Play Feels

Procedures favor clear fictional positioning and fast adjudication over exception lists. A thriving open‑source ecosystem: hundreds of free supplements, adventures, and optional modules expand the core without bloating it.
