Also by Sierra: Quest for Glory.
Quest for Glory is a series of hybrid adventure/role-playing video games (and later Action/RPG for game 5) designed by Corey and Lori Ann Cole. The series combined humor, puzzle elements, themes and characters borrowed from various legends, puns, and memorable characters, creating a 5-part series of the Sierra stable.
Although the series was originally titled Hero's Quest, Sierra failed to trademark the name. Milton Bradley successfully trademarked an electronic version of their unrelated joint Games Workshop board game, HeroQuest, which forced Sierra to change the series' title to Quest for Glory. This decision caused all future games in the series (as well as newer releases of Hero's Quest I) to switch over to the new name.
HeroQuests are, of course, part of the Gloranthan Universe, wherein a RuneLord embarks upon a sacred journey to perpetuate the myths of his chosen cult.
