From the back cover:

A Marvelous Campaign World
Glorantha is the most elegant, original, and imaginative fantasy roleplaying campaign setting ever designed. Glorantha's detailed cultures, histories, and myths are shaped by gods, heroes, and magic, yet plausible and logically self-consistent.
A Complete Roleplaying Game
RuneQuest Deluxe contains the necessary game systems (combat, skills, and magic), comprehensive descriptions of major creatures and races, extensive gamemaster design and staging notes, a scenario, and an introduction to the world of Glorantha."
