Flight simulators are either technically accurate or easy. Microsoft's was the more technical but it limits market appeal as it's hard to get into unless you are really into airplanes. Technical simulators are very niche products (like FlightGear) in that the community surrounding them gets really into the details even building simulated cockpits with multiple screens and instruments. They have events where some players do nothing but act as dedicated flight controllers for airports.
Train simulators tend to be simpler and can be handled by the "Thomas the Tank Engine" market segment. I would expect the Train Simulator to be finished as it's more likely to succeed but it wouldn't be the first time it was cancelled: http/en.wikipedia.org/wiki/Microsoft_Train_Simulator
Just look at Steve Balmer what a joke.He should be fired as CEO as he is ruining Microsoft.
Look at Microsoft's stock value since last year it has gone down in half especially over Balmer's Vista fiasco.
Axing the Microsoft Flight Simulator series and laying off the employees at Aces Games Studios is complete stupidity.The only reason that I and hundreds of thousands of other customers built a new PC and bought another copy of Windows was to run FSX and get super detailed and complex 3rd party aircraft (especially from a2asimulations).No more flight simulator series then no need for me to build another PC and buy a newer version of Windows.Microsoft you have made a huge strategic blunder.
I wish someone would bring back Mech Warrior, MS why!?!?
If you plan to shut down a franchise, do what the makers of FreeSpace did, go Open Source (LOL Like MS would ever open any of their source) and let the product live on by the people who were your best fans.
