During the 1990s, joysticks such as the CH Products Flightstick, Gravis Phoenix, Microsoft SideWinder, Logitech WingMan, and Thrustmaster FCS were in demand with PC gamers. They were considered a prerequisite for flight simulators such as "F-16 Fighting Falcon" and "LHX Attack Chopper". Joysticks became especially popular with the mainstream success of space flight simulator games like "" and "Wing Commander", as well as the "Six degrees of freedom" 3D shooter "Descent". VirPil Controls' MongoosT-50 joystick was designed to mimic the style of Russian aircraft (including the Sukhoi Su-35 and Sukhoi Su-57), unlike most flight joysticks.
