I think you are quite right there, Rick.
It has also been really interesting to hear how Asobo/Microsoft continues to work closely with developer companies, such as PMDG and Carenado, to implement new, core-sim items that those dev companies ask for and then they just become elements of the sim.
Don, with regard to seeing a Beech 18 in MSFS, Carenado of course produced the best flight sim example to-date for FSX/P3D. They have said that they are working on bringing every one of their FSX/P3D aircraft over to MSFS, so I have been crossing my fingers that they get to the Beech 18 sooner rather than later.
