Rush’s career has lead him to several game studios such as Guerilla, Square Enix and Telltale. With a strong belief that games can be art, he wrote an essay for the “Art of Video Games” exhibition at the Smithsonian Institution’s American Art Museum on ambiguity’s role in the game “Limbo.” He has also worked in motion capture for film, concept art, board games, anime, and traditional media.

He taught at Indiana University for many years before joining RPI.
