Credited as executive producer on Grand Theft Auto III, Houser's responsibilities on that game were, in his words, to be "militant on ensuring the game had a look, a sound, a story and a feel that worked." He also appears as an easter egg in GTA III and GTA Vice City - In both he takes on the role of the Ammu-Nation clerk.
