2 complete 4 disc Flight simulators, Virtual Pilot 3D 4 Discs New Sealed  for both mac & PC  & Pro Flight Simulator Suite 4 Discs that has been opened and most likely used before but there are no scratches or blemishes so cant say for sure however, it reportedly has 90 different aircraft and 25,000 real airports. The 4 disc set on ech is comprised of disc #1 being the Main program - aircrafts- manuals and  discs 2-3-4  world scenery. Small print on the back of Virtual Pilot reads non-returnable and non refundable so I am offering the same policy so please make Sure this is something you want as I am not accepting returns on these as I would only test the opened simulator but only have one arm and am not familiar with this type of item and I'm betting that my laptop that came over on the Mayflower would not be able to handle these and lock up, so please make sure these are something you want and ask any questions prior purchasing and I will do my best to answer them. Thank you.
