Sierra On‑Line released Roberta Williams’s King’s Quest I, a groundbreaking 2.5D adventure game.
In May 1984, King's Quest: Quest for the Crown was released by Sierra On-Line, pioneering the use of animated graphics in a pseudo-3D environment for adventure games. Developed by Roberta Williams, the game enabled players to navigate their characters in front of and behind objects, creating an immersive experience unlike anything before. The game's design required more complex programming and graphics than had previously been standard, signaling a new era for gaming technology and storytelling, which positioned Williams at the forefront of industry innovation.
