The world of the King's Quest games is largely immersive. It encompasses over ten different and beautiful worlds. These include Serenia [King's Quest V], Tamir [King's Quest IV], Kolyma [II] and Lledor [III]. King's Quest VI is univerally known as the high point of the series for it's in depth plot, and it's landmark 3D graphic introduction movie, and it's great voice acting. King's Quest V was the most innovative King's Quest since Quest For the Crown's 1984 release. Released in November 1990, V's remarkable graphics and use of compact disks was amazing and it became the highest selling computer game in history. King's Quest VII's release in 1994 was met with mixed reviews but sales were high. In 1998, King's Quest VIII was released to very poor reviews and poor sales and was considered by many to not be a real King's Quest because of it's Quake like violence and graphics.
