Tron for the Atari 2600, 1982
This particular ad from 1982 is for two Tron games for the Atari 2600 by Mattel (which were also available on the Intellivision).
The first game, Tron Deadly Discs, was released initially on the Intellivision in 1981 and later adapted to the Atari 2600. The idea is to defeat enemies by throwing your disc at them and blocking or avoiding the ones thrown at you.
The second game, Adventures of Tron (or just Tron), was an adaptation of the arcade game of the same name. This was a fairly good adaptation on both the Atari 2600 and Intellivision given the limits of those systems. Both Tron games are must haves for fans of the film. I always preferred the Atari 2600 joystick to the Intellivision controllers so I would pick those versions of the games but both the Intellivision and Atari 2600 do a pretty good job with them.
