King's Quest is the adventure game that started Sierra's best-known series. IBM published it for its new PCjr computer in May 1984 after asking Sierra On-Line for a game that would show off the machine's graphics. Roberta Williams designed and wrote it, and a team of six programmers and artists worked on it for about 18 months. IBM paid US$700,000 toward development, which made it Sierra's most expensive title at the time.
It was Sierra's first game with a visible hero walking around the screen and the first built on the Adventure Game Interpreter (AGI) engine. Sierra then released versions for the Tandy 1000, Apple II, Atari ST, Amiga, Macintosh and MS-DOS, and a Sega Master System port came out in 1989. The game was never released in Japan.
In 1990 Sierra remade it as King's Quest I: Quest for the Crown on its newer SCI engine.1
