The 11th Gold Box game, and the final one I played. I think this is the best game in the series by a narrow margin; Pool of Radiance is better paced and has mercifully few random encounters, but DQoK has greater enemy variety, more complex area design, and a wider range of useful spells. And while it does have areas with unlimited random encounters, they're not nearly as annoying as in Pools of Darkness. I also think it's the best written Gold Box game, but that doesn't mean all that much.
