I am a simulator junkie. Even though I have never heard of this one I have owned G2 and Currently own AFP. Just a bit of advice make sure you buy a sim based on funcionaltiy not based on the best graphics or the most expansive 3D scenarios. I love to fly 3D and IMO AFP is the best sim for learing that. If flying is your thing and general basic aerobatics I am sure any of em will do. If you like helis and want realism in learing how that react I have heard from heli pilots that G2 is the best for that. just be careful not to buy a sim thats no more than a sophistcated video game. Unless thats what you are looking for then I would try Reflex. By far they prob have the best Graphics. IMO for flight physics and realism in flying AFP is the most acurate. And their developers actually make simulators for the military. Thas pretty cool.
