I voted "Something Else" and that something else should have been pretty much "All of the Above"
Im a Pilot (For training) - FSX can help you stay on top of instrument skills you rarely use like Holding
Not only is GA my hobby, but so is the entire MSFS line up since my first time playing MSFS 2.0 back in 1984 (

its always interesting to try new challenges in FS that you might not have the opportunity to do in real life, for example right now im flying the Maule M-7 from my home in Texas out to Long Beach, Up to Seattle, east to Billings Montana, then to Chicago, Charlotte NC, Miami, Panama City Florida, then back west to Mobile, AL back to my home town.
plus FSX offers a few things that FS9 Doesnt - particularly in Multiplayer. Plus if you have a machine that can run FSX at full sliders and have it still run above 13 FPS in a place like L.A. or New York you will really be able to enjoy the way it looks.
