Marble Madness Geneology

Marble Madness had one sequel planned, but otherwise stands alone its family tree.

1984 - Marble Madness - Beat the clock and the other player as your marble rolls through six different races.

1991 - Marble Madness II: Marble Man - Atari hoped new enemies, three-player action and talking marbles would help bring younger arcade gamers to this sequel, but poor test marketing led to the game's permanent shelving.
