Space Wars was the brainchild of Larry Rosenthal, an MIT graduate who was fascinated with the original Spacewar! and developed his own custom hardware and software so that he could play the game. Rosenthal shopped the game to various manufacturers, demanding an unheard-of 50% split of the profits. Only Cinematronics was willing to take him up on the offer.
