During the eighties and early nineties, the world of Adventure Games belonged to Sierra. Games series like King's Quest, Space Quest, Police Quest, and Quest for Glory, established the company's love of quests, and in 1989 there was Laura Bow: The Colonel's Bequest, following in the same naming format of putting the word "quest" somewhere in the title of each game. The game was created by Roberta Williams of King's Quest fame, and borrowed elements from Williams' Mystery House, created in 1980 and known as one of the first graphical adventures.
