Just my opinion, which may or may not represent many others. I'm an amateur pilot, and a professional air traffic controller. I also work many hours, have kids and a very busy life. I just don't have the time or resources to learn and remain proficient in the "high" fidelity aircraft. But thankfully the FC3 type aircraft with PFM and simple cockpits relieves me of that issue. In those aircraft everything goes back to the basics. Managing energy, using your combat systems to make plans. Cranking, 9-3 lining, understanding basic airmanship, functionality of the pulse-doppler effect, understanding basics of proportional navigation ect ect.... All the same things that makes one a good pilot in "low"fidelity aircraft are the same things that make you a good pilot in a "high" fidelity aircraft. The difference is one person spent alot more time remember checklists and procedures and the other did not. Personally already have to remember plenty of those and don't wish to continue it in my little free time.
What I'd really love to see is newer versions of the redfor aircraft IE, newer Su-27s and Mig-29s. I know I know, they want to but they have issues, but I really hope they keep pushing.
