M.U.L.E.

M.U.L.E. is a seminal multiplayer video game by Ozark Softscape. It was published in 1983 by Electronic Arts. It was originally written for the Atari 400/800 and was later ported to the Commodore 64, the Nintendo Entertainment System, and the IBM PCjr Japanese versions also exist for the PC-8801, the Sharp X1, and MSX 2 computers. While it plays like a strategy game, it incorporates aspects that simulate economics.
