Published by Electronic Arts, Inc. and developed by Ozark Softscape, this seminal multiplayer video game released in 1983.

The game is a kind of an exercise in supply and demand economics. It involves competition among the four players. Players can choose a race of their colonist, providing unlike advantages and disadvantages, which can be paired to their individual strategies. In order to win, players have not only to compete against each other, but must also cooperate for the survival of the colony. They will have to deal also with periodic random events like a run-away M.U.L.E.s, solar flares, and theft by space pirates. M.U.L.E. features a balancing system for random events that impact the only one player. It means that favorable events never happen to the player now in first place, and poor events never befall the player in last place. This is applied at any time a difficult situation takes place in the game. The player in the losing position wins the tie automatically.
