FSX does have some realism sliders/options, simple ones such as unlimited fuel, automixture and auto-rudder and the like, and some sliders for things like crash tolerance and gyro and I believe torque. But nothing that truely changes the flight feel.
It also offers some some shurtcuts, for instance to start the engines, or aut. set the altimeter.
But my experience with these keyboard/mouse style games is far more arcrady then fsx with all these helpers on.
Personally I see 3 types of "flyers". Arcade type flyers who just want to enjoy scenerary and shoot at stuff, intermediate flyers who enjoy a bit more realistic planes, such as the default MSFS offerings, and people who strive for every bit of realism they can get, they are seperated by mostly systems depth, as opposed to flight handling, which seperates the first two, along with very simplified systems.
Now, let's only look at the first two groups, nobody expect Outerra to cater for the third, this is where aftermarket comes in. Realistic planes take years upon years to simulate right.
If Outerra Product X wants to cater to both these groups at the same time, then IMO they will need two seperate vehicles (eg. Two Apaches). They can use the same external model, but I don't think the two groups will want eg. the same weapons systems/display. Or the same hud. Or the same Autopilot. Or the same Radio panel. Or the same GPS device. Using a middle-ground for systems, and just switching out the handling will leave neither group happy. That was my point, I might be wrong. Does that make sense?
And yes, it was my (poor) attempt to light things up a little around here, thread appeared to deteriorate (which was my fault, admittingly).
