This scam has been going on for many years.
Basically, we are all looking for the Holy Grail of sims. However....
Firstly, a warning sign would be the total lack of Proflight forums on all the usual simming sites!
If it looks too good, it IS too good!

It is actually a boxed version of an old outdated version of FlightGear which is, in actual fact, pretty decent & free.
A simple google search for Proflight flight simulation will take you to http://lumenosity.blogspot.co.za/2011/0 ... -scam.html
So, buyers beware, & do your homework before spending money on trash!
Go & support the FlightGear crowd, it is actually a great sim, good scenery & planes & FREE!!http://www.flightgear.org/
