This may have already been covered - I didn't have time to search through all the forums.

I have an iMac and want a simulator to fly. Does anybody know the difference between the Aerofly Professional Deluxe and Aerofly 5.7? The 5.7 costs $140.00 more and all I can see is that you can fly with friends and has 4D (what is that?) graphics.

I just want a good selection of airplanes / gliders and don't really need the internet flying experience with friends. I do want realistic flying fields and good physics and maybe the ability to modify control throws, power levels, wind, etc.

Is the 5.7 worth the extra money?
