Orbiter 2010 takes flight simulation to a whole new level. Instead of being limited to airplanes flying from Vancouver to Hong Kong, Orbiter takes players to the Earth's orbit, providing a realistic space flight experience which respects the laws of physics.
You start your flight by launching from the Kennedy Space Center, rendezvous'ing with the ISS above the Earth's atmosphere. From there, you're able to fly some realistic spacecraft giving you the ability to simulate some futuristic spacecraft.
The learning curve of this simulation game is pretty steep, so you're going to have to take some time to learn exactly how space flight works -- it's nothing like Microsoft Flight Simulator.
With Orbiter 2010, you are also able to design rockets and access the many addons that have been created by the community surrounding Orbiter.
Have a safe flight!
