Superworld is a
superhero-themed
role-playing game published by
Chaosium in the
1980s. Written by
Basic Role-Playing and
RuneQuest author
Steve Perrin[?], Superworld started life as one third of the
Worlds of Wonder[?] product, which also included a generic fantasy setting, "Magicworld", and a generic
science fiction setting, "Spaceworld", all using the same core Basic Role-Playing rules. Only Superworld became a game in its own right.
