Not much of an improvement on the first 2 Kings Quests. I really like the concept of quest-based games - like NWN or Diablo now, I guess. But Sierra never really managed to get it right. The gameplay is not very good, since everything is keyboard-based and 2-dimensional. The storyline is reasonably convincing but that's about the only thing that's good about this.
NO replay value as far as I'm concerned, I wouldn't recommend it. It was OK at the time, but now - no way.
