As seen on many internet pages, a new flight simulator called ProFlightSimulator has been announced. Actually this flight simulator software is pretty cool.
BUT, if you don't like to spend about 80.- USD, you can get completelly the same downloadable flight simulator software on www.flightgear.org!
So, flightgear is originally an open source software, built by many software developers for free! Everyone can download this flight simulator software.
The flightgear open source developers actually created a new wiki page for anxious customers.
As many people are aware, there is a new flight simulator product that is being widely and actively marketed at the moment - Flight Pro Sim (also promoted as ProFlightSimulator, FlightSimPro, Earth Flight Sim, FlightProSim, Real Flight Simulator). This product is a direct copy of FlightGear.
