Takes off the training wheels and makes things much more realistic.
Real solar system, scales and values no longer on easy mode, much more complex and accurate physics calculations for orbital manuevers, much more realistic aerodynamics model.
If you can get an ‘Oberth Kuiper’ manuever to work in all that, a NASA employee might actually take at least momentary notice.
