I have owned and flown every flight sim sold since FS1 including the non-Microsoft sims. I am a pilot and use high end gear for simming. I am impressed with the graphics. I wish we could get the engine into P3D 
I have now flown several aircraft in successful IFR flights including the King Air, TBM ,and 172. ATC works but still needs tweaking.
Would be great to see a selectable level of complexity for the aircraft with the expert level having all knobs switches systems etc functional in the aircraft. Current complexity would be Student Pilot, Intermediate and then Expert or ATP level.
Anxious for Active Sky to become functional with MSFS 2020. The volumetric clouds are too defined on the edges yet not sharp in some respects.
Just some of my observations to date. It is fun to fly in the environment and anywhere in the world. I expect to see great things from MSFS 2020 if it can be matured as a true simulation for those wanting the challenge. My hat is off to the development team.
