Basic Role-Playing

Basic Role-Playing (BRP) is a role-playing game system which originated in the fantasy-oriented RuneQuest role-playing game rules. A percentile skill-based system, BRP was used as the basis for most of the games published by Chaosium, including Stormbringer, Worlds of Wonder, Call of Cthulhu, Superworld, Ringworld, Elfquest, Hawkmoon, Elric!, and Nephilim. However, Pendragon (acquired in 1998 by Green Knight Publishing, and 2005 by White Wolf), while related, has sufficiently different mechanics that it can be seen as a separate system. The BRP standalone booklet was first released in 1980. Two years later it became part of the Worlds of Wonder boxed set. The first edition boxed set of Call of Cthulhu included the booklet as its character creation rules. Greg Stafford and Lynn Willis are credited as the authors.
