From Brian Moriarty's tribute to Dani Bunten: "M.U.L.E. was multiplayer from the ground up.It used the joystick array of the Atari 800 to connect four people in an unprecedented example of computer-moderated parlor gaming. By combining the resource management of Cartels and Cutthroats, the auctioneering of Wheeler Dealers and the futuristic setting of Cytron Masters, M.U.L.E. sustained an exquisite play balance of teamwork and rivalry, bitter cooperation and delicious treachery. Although the original version sold only 30,000 copies, M.U.L.E. developed a base of passionate fans that remains active even today. It is required study for anyone interested in the design of multiplayer computer games." Highly recommended.
