In 1982, he was hired by the Computer Division of Lucasfilm to help start Lucasfilm Games. Langston wrote the music for and contributed to the game design of Lucasfilm Games' first two releases, Ballblazer and Rescue on Fractalus!. In fact, for Ballblazer, Langston created a "fractal music system," which allowed the game to improvise music (from an initial tune) based on what is happening in the game. Langston later left Lucasfilm Games for Bellcore (now Telcordia Technologies).
