Collector interest
An ASCII NES port of Wizardry's second scenario, Knight of Diamonds, released in the United States in 1990. A direct sequel to a cornerstone of Western computer RPGs, this console conversion stays a niche title, more common than rare, its modest value reflecting demand from connoisseurs of first-person dungeon crawlers. The collecting interest rests on the Wizardry lineage and ASCII's NES work rather than on any pronounced print scarcity.
