What’s Inside
Basic Roleplaying: Universal Game Engine is the complete guide to BRP—the same system that powers Call of Cthulhu, RuneQuest, Pendragon, Rivers of London, and countless others.

BRP’s Universal Game Engine is available royalty-free for personal and commercial use under the ORC license. Use these rules, and focus on creating your worlds, scenarios and even books to sell!

This book contains the core system rules, as well as character creation, advancement, monsters and antagonists, as well as GameMaster advice.

A Seamless Core Mechanic
BRP Character Sheet Example
In BRP, success and failure are always determined by the roll of a D100. Comparing that roll to the relevant Skill, Characteristic, Ability, or Power, you succeed if you roll under the target number.

This means every stat on your character sheet clearly indicates to you the likelihood of success.

Natural Character Growth

Characters in a BRP game evolve based on what they do in-game. If you fire a gun, that skill may increase.

If you want your character to learn magic, get better at driving cars, lassoing horses, or even repairing a spaceship, then your character will do so by using those skills!

Deadly & Tactical Combat

The core BRP rules present easy-to-learn and equally easy-to-teach combat mechanics that allow players to react to attacks—you don’t just have to wait for your turn in order to have an impact on combat!

Conflict in BRP can be deadly, and every roll (attacking, fighting back, dodging or otherwise) is integral. This makes for a thrilling, high-octane experience with a system that does not slowdown the overall flow of play.
