Scott Miller (born 1961) is an American video game designer, programmer, and entrepreneur best known for founding Apogee Software (which later became 3D Realms) in 1987.
Starting with the Kroz series for MS-DOS from that year, Miller pioneered the concept of giving away the first game in a trilogy—distributed freely as shareware—with the opportunity to purchase the remaining two episodes.
Miller started as game programmer, but now handled primary business duties of 3D Realms, as well as producing and co-designing all third-party games associated with the company, including Wolfenstein 3D, Raptor: Call of the Shadows, Terminal Velocity, Max Payne and Prey.
Upon success with this model with the seven Kroz episodes, Miller left his full-time job in early 1990s and devoted full efforts into growing Apogee.
GameSpot named Miller as number 14 in their listing of the Most Influential People in Computer Gaming of All Time.
