The Activision Decathlon is a classic sports video game released for the Atari 2600 in 1983. Designed by David Crane, it simulates the ten events of the athletic contest known as a decathlon. Players compete in events such as running, long jump, shot put, high jump, and javelin, trying to master the timing and speed needed to win a gold medal. It was renowned for its use of the Atari joystick and the physical rigor it demanded from players, often leading to the 'Atari thumb' phenomenon.
