 The concept for the game was born out of an attempt by designer Ed Logg and engineer/technician Doug Snyder to create a first-person video game without specialized hardware.In 2005, Logg recalled that he had trouble with the controls for the game—both building controls that worked with the game design and getting players to realize they could rotate the joystick to turn the in-game characters.Because of these difficulties, Logg was unsure if the game would enter mass production.
