There's some extremely frustrating stuff about this game, but at the same time it's a lot more inventive as a result. The real time clock that ties to game elements, the spellcasting that also doubled as DRM, and the fast travel system are all interesting innovations that help make this the most interesting out of the first three King's Quest games to me. The story is also pretty solid, and it has one of my favorite subtitles in gaming. I'm a sucker for dumb puns.
