Two earlier text adventures, Adventure in the 5th Dimension (1983) and Crash Dive! (1984), were published in the pages of ANALOG Computing, a magazine for Atari home computer enthusiasts at which Moriarty was employed as Technical Editor. Screenshots of a third game, Tachyon, were previewed, but the game was never published in the magazine. Tachyon was an adaptation of Atari's Quantum arcade game.
His first graphic adventure game was Loom, published in 1990 by Lucasfilm Games. He also collaborated with Ron Cobb on the design of Loadstar: The Legend of Tully Bodine (1994) for Rocket Science Games, and worked on an unreleased incarnation of Steven Spielberg's The Dig (1995), some elements of which were included in the released version of the game.
Moriarty now lectures as a Professor of Interactive Media and Game Development at Worcester Polytechnic Institute. On occasion, he delivers public lectures, one of which has been turned into an amateur dramatic production.
