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.
