Including three game cartridges.
The console itself came out in 1977. The kit contains 2,532 pieces and will be available for order on August 1 for $239.99.
In addition to the console, the set includes a joystick (also from Lego) and three cartridges with the most popular Atari games: Asteroids, Adventure and Centipede. They can be inserted into the console, but you will not be able to play.
