IS PROFLIGHTSIMULATOR THE SAME AS FLIGHTGEAR?

Dan Freeman of ProFlightSimulator.com gives an emphatic NO
ProFlightSimulator is very friendly to new users.

• The installation is very easy. Nothing technical or complicated. You simply plug in and play.
• Updates are available monthly as well
• New aircraft models are added regularly.
• With a team of paid developers, ProFlightSimulator can offer ongoing improvements.which include:

• Improving joystick interface (one-click configuration with all major
  flight control hardware)
• Intergrating VATSIM and other network support.
• Constant development of new aircrafts and new sceneries.

ProFlight Simulator is an open source, stand alone flight simulator. It may be based on Flightgear, but it is definitely NOT the same..

PriFlightSimulator is used On Television Episodes & Professional Flight Schools.  It is the most realistic flight Simulator to date.
