The whole "Flight" release is a bit odd to me. After FSX, Microsoft basically shut down the project, cut loose all the programers and, to top it off, sold the intellectual property and code to Lockheed Martin. Not sure why they would take so many steps backwards and then take a stab at putting out a flight simulator that isn't up to their own standards. Obviously, it didn't pan out.
Anyway, I think the good news is FSX is being developed by Lockheed Martin now under the title "Prepar3d." And, they seem to be putting out updates every 5-6 months. Even though I never thought I'd be interested in commercial flight sims, being able to fly anywhere on Earth is pretty fun.
