Game Classics: M.U.L.E.’s Four-Player Economy

A food shortage in M.U.L.E. costs you time. An energy shortage can stop production altogether. Ozark Softscape’s 1983 release for Electronic Arts made economic decisions matter long before anyone reached the auction screen.

Players develop a colony by fitting robotic M.U.L.E.s for particular jobs and leading them onto their land. Food determines the time available during development; food and Smithore producers need energy to work. The practical lesson is immediate: expanding your holdings without securing supplies can leave expensive machinery doing absolutely nothing.

The auction turns those dependencies into a shared spectacle. Sellers move down the screen to lower their asking price; buyers move up to raise their bids. When they meet, goods change hands. A timer keeps negotiations moving. You can see somebody refusing your price, which is considerably more personal than receiving a disappointing spreadsheet.

The C64 version accommodates four players without demanding four joystick sockets. Up to two players use keyboard controls during action rounds; during development, players can use any available joystick. Its reference card also specifies 50% food spoilage and 25% energy spoilage for stocks carried forward. Hoarding has a cost, so a surplus creates a reason to trade rather than simply sit tight.

Designer Danielle Bunten Berry later described the auction as a favourite element of the design. Its achievement was making prices visible as movement: a few characters on one screen could convey stubbornness, urgency and a very poor offer.
