I realize the DC6 is not a "Heavy Metal Jet", I was just saying that PMDG has started testing the waters with X-Plane, and admitted themselves that X-Plane offers features they were never able to try before with FSX etc.
I am trying to give you a compliment for one thing. FS2Crew is a great product, I hope to support you again soon.
Seeing as you have already done PMDG and Aerosoft, I might suggested converting the A320 version for X-Plane use with eg. the Flight Factor A320 study sim that will be released any day now, for example. You already have all the dialogue etc. Convert it for XP and test the water.
A few friends of mine and myself have started a Virtual Airline quite some time back, and I can tell you that almost everyone I heard of who have tried X-Plane, has not gone back to FSX.
And I am not trying to start the X-Plane vs FSX / P3D battle, I was an avid supporter of Microsoft Flight Simulator since 5.1. When my friend (new friend at that time) tried to get me to try X-Plane, I had all the arguments, and defended FSX as if defending my wife's honor. But since I tried XP10 I have not gone back to FSX and upgraded to XP11 as soon as it became available. I am a real life pilot, and nothing beats the Flight Dynamics and terrain mesh amongst others out of the box. (And yes, I did try P3D.)
Point I'm trying to make, is X-Plane has grown significantly and has a huge following. And I wish you would consider giving it a try.
