The Activision Decathlon on the Commodore 64 is a joystick-busting Olympic-themed sports game where up to four players compete in ten track-and-field events—100m, 400m, and 1500m races; 110m hurdles; long jump, high jump, pole vault; and discus, javelin, and shot put. You hammer the joystick left and right (or waggle it in a tight arc) to build speed, then time button presses and angles for jumps and throws, with performance in each event converted into points toward an overall decathlon score. It’s simple and very repetitive, but the combination of multiplayer rivalry, frantic physical input, and the challenge of chasing real-world decathlon-style point totals made it infamous both as a party game and as a destroyer of cheap joysticks.
