Black Gold on the Commodore 64 (also known as Oil Imperium) is a hot-seat business simulation where up to four players run rival oil companies competing to dominate the world market. You pick one of four victory conditions—best results after three in-game years, first to $60 million, 80% market share, or simply bankrupting all opponents—then buy licenses and fields across eight regions (from Alaska and Europe to the Gulf and Indochina), drill for oil, build pipelines, store and sell your crude, and watch monthly financial reports. Beneath the icon-driven strategy screens are short arcade-style sequences for manual drilling, laying pipelines faster than competitors, and extinguishing burning wells, while a full suite of dirty tricks—sabotage, arson, tank theft, financial skulduggery—and countermeasures like hiring detectives and security firms adds a gleefully nasty edge to the corporate warfare.
