DynaMicro's Dungeons of Daggorath, released in 1982 for the Tandy CoCo, is one of the earliest examples of a first-person computer role-playing game. I recently had the chance to play this innovative title a few weeks ago as part of my research on the Tandy CoCo, and I must say that I'm impressed with the title--and can easily see why the game has managed to retain such a devoted cult following that's lasted nearly a quarter of a century. So, what makes the game so great? What I want to talk about here are three features--the immensity of the game world, the intensity of the action, and the creative use of sound. Although Tandy's CoCo arguably suffered from a rather dismal game library, DoD really stands out as a true classic.
