In 1984, Marble Madness was the first game for the new Atari System 1 and Atari Games demonstrated the technical superiority of this new piece of hardware with this outstanding game:
-It was the first game with such impressive Pseudo-3D-Graphics.
-It was the first game with true stereo sound.
-It was the first game with a kind of film music, the music really supports the pictures and keeps the player in suspense.
-It seems to be the first game that hardly had any repetitive elements during the levels and that had a real "end", the player could win against the machine.
