This is a sourced index of commercial space flight simulation games. The list is categorized into four sections: space flight simulators, space flight simulators with an added element of combat, space combat simulators with an added element of trading, and unreleased space flight simulators.
A space flight simulator game is software that allows the operator to experience space flight with the added elements of gameplay. There are many different types of simulators. These simulators range in purpose from pure simulation to sheer entertainment. Space flight occurs beyond the Earth's atmosphere, and space flight simulators feature the ability to roll, pitch, and yaw. Space flight simulators use flight dynamics in a free environment; this free environment lets the spacecraft move within the three-dimensional coordinate system or the x, y, and z (applicate) axis.
