I wish there was, in MFS2020 or other flight sim game, some structured gameplay other than "select airport and spawn". TO me it's the biggest flaw across pretty much all civil aviation simulators.
Something like Euro/American Truck Simulators do very well, where you would start as a small time pilot flying a Cessna or as some backwater bush pilot taking odd jobs to earn cash, and later start your own company and start buying your own planes and creating your routes.
I guess this would need to create another game layer to simulate economy, route supply/demand, etc, but sometimes it gets boring to fly a plane "just because".
