On an Atari system at a friends house in 1984. The Atari had 4 joystick ports for game play. Then when it was released for the Commodore 64 I had to get it. Played it through the college years. Still have (2) copies with the original packaging and an SX-64 that we get out occassionaly to play. Also had it on the Nintendo but it was not the same. This should be fun!!
