Powering some of the most influential and celebrated roleplaying games of all time, Basic Roleplaying is presented here in an easy-to-use, intuitive, and accessible quickstart. The system is at the heart of Call of Cthulhu, RuneQuest, Pendragon, and many other popular games. This quickstart gives you an easy entry point into the Basic Roleplaying world.
Basic Roleplaying is an ideal beginner’s game, but also appeals to those who wish for clear, concise rules that are easy to explain in play. Characters are based on what they can do: defined by skills and abilities rather than abstract roles or classes, and they advance by using their skills successfully in play.Inside you’ll find:
- Core rules for adventuring, conflict, and combat.
- Rules for creating characters from a variety of settings.
- Three complete adventures spanning three settings: swashbuckling France, a hostile alien planet, and a ruined temple devoted to an evil god.
