Realistic pilots?

[Furio]

In my opinion, we should realistically consider the difference between simulating air combat – as good as it is our beloved simulator – and any attempt at replicating reality, which is basically unattainable with known technology.

As fatigue is not the same for everyone, so it is courage or fear. Flying in a sim, you may be afraid to lose your points, but you never risk anything real, let alone your life. And this makes a huge difference. Playing with a sim, it comes natural to readily accept unreasonable risks for small rewards, this being anything but realistic.
Respectfully, my opinion is: any form of “artificial fatigue” should be avoided, or introduced as an option.
