"Descent to Undermountain" was generally poorly received. The decision to use the "Descent" graphics engine was cited as a design issue, as it required heavy rewrites to the code in order to support an RPG setting such as Undermountain. According to game designer Eric Bethke, bugs, poor AI, the unappealing and shoddy nature of the graphics, and several other issues have attributed to a general consensus of the game as an example of a title that was pushed to release before it was ready. Technical issues existed in the concept which delayed development, forcing redesigns and re-engineering. Ultimately the "quick change" to Descent's rendering engine proved to be extremely challenging which exceeded the technical understanding of the corporate leadership who were resolved to predetermined delivery dates. This lack of understanding led to a hurried development cycle, and the game was maligned by Bethke as "a classic example of a game that was shipped too early."
