Prison Tycoon is a business simulation computer game developed by Virtual Playground and published by ValuSoft in July 2005 that puts the user in charge of a prison. Objectives are to keep the prison running, keep the staff happy, keep the prisoners in line, all while trying to make money. Users are allowed to choose between a New England prison, a modern U.S. Southwestern-style prison, and a West Coast-style prison modelled after San Quentin. Also, THQ Wireless released a version of Prison Tycoon for the iPhone in May 2009.
