1) The default X-Plane 10 aircraft has just a fake G1000. The payware has a G1000 that works like the real thing (albeit with reduced functions) and is the ONLY X-Plane aircraft with a terrain view on its moving map. 2) In my review I was able to fly by the numbers given in the manual. What do you mean by prop effects? You can change prop settings and it affects performance, of course. 3) It is 64 bit ONLY. Summary: Highly recommended.
