Man, Myth & Magic (1982)

"A role playing game of man's greatest adventures."

User summary and back of box:

Start off as a Roman Gladiator and reincarnate as ... "an Egyptian Sorcerer, a British Druid, even, perhaps an Irish Leprechaun to face the might and the mysteries of the ancient world!"

Boxed set contains three books:

Book I: The Basic Rules (24 pages)
Book II: The Advanced Rules (40 pages)
Book III The Adventures Book (52 pages)
plus a pad of character sheets and several perforated maps and charts

The latter book contained the first four episodes of a continuing adventure that was ultimately fleshed out to nine by additional adventure modules, all of which required the advanced rules.
