Well, Flight Sim World I have looked at, and it is not much better if any
better than FSX. This is because it is still based on FSX and its engine.
It has a few tweeks to the user interface, but there is nothing to write
home about. It would be nice to get a similar program to IYP for xPlane.
The down side to xPlane is that you seriously need a high end system for it
to run well at all, and currently there is no way for a blind person to fly
with that software.
