Before I start:
Brandon stated "What I would like to see are pure default comparisons between FSX and Flight. Obviously, if you have Flight DLC content, that is alright to use, as it only adds locations and planes. But adding stuff to FSX that changes the way the sim actually looks isn't a good comparison. "
Seriously, I respect you defending what you like BUT we must compare to what we have NOW and what we can replace it WITH to make an informed decision.
You expecting us to compare a 2006 default to a current to make that choice, when hell we don't even have access to international areas is just insane

I believe most choose FSX above MS Flight because no MS Flight user can fly in & take a realistic looking screenshot like most FSX users can in FSX.
Therefore one cannot compare FSX with MS Flight.
The one is a game and the other a pure bred & well expanded simulator.
However,
It just shows that Flight, besides that it is a game, cannot offer the visual and realistic experience FSX can offer and NEVER will due to MS intent to avoid 3rd party development.
As for performance, OF COURSE flight will perform all nice and wacky. It has NO AI, NO ATC and it is one tiny bubble you fly in.
Very little in that bubble compared to FSX.
Add all that to Flight and we talk again about performance. Looks like MS's intent to ellude "gamers" that flight is smoother then FSX worked well.
Please do not get me wrong, I would have used flight if it was a simulator and PLEASE do not tell me it is.
NO AI.
NO wider selection of AC.
NO choice of "where to fly"
Quite frankly, products like P3D will likely become the future follow up to FSX.
P.S: Please make it a rule that screenshots of MS Flight may only be posted where we post pictures of OTHER non simulator screenshot posts eg. the likes of COD etc.
