As I understand it the technical limitations of FSX/FS9 don't allow as many polygons as with XPlane. Please spend your polygon budget in the cockpit and not a cabin/crew area. Make the most beautiful cockpit you can (with smooth/round gauge fascias, and great night lighting) and you will have the FSX/FS9 crowd talking. XP needs a super high quality 747, its the glamor plane of all time. You can be the guy that convinces 1000's of FS9/FSXers to buy XP just to try your 747.
