Rest assured, it's a real simulation. I know that people with an ax to grind
will insist otherwise for a lifetime, but that doesn't change the reality.
Simulators have come a long way, and the mere fact that a simulator runs on a
PC doesn't make it "unreal."

A Crash within MSFS is just a failure with no consequences.

A crash in every simulator is like that. That's one of the advantages of
simulation.

If you play MSFS regularly, you should know it's limitations.

I do. I've listed them on several occasions.

I just tried you "experiment" and were scared by the low climb rate of
the Cessna in that altitude.

I can't say that I was scared by it, but I found it pretty lame. I was
heading west so there wasn't a lot of terrain to avoid.

Even the real big flight simulators are limited to the input data they
have. And to my knowledge, not much data from unusual flight envelopes
(stalls, spins whatever) is inserted in these things.

That's why they are not used to practice spins. Any pilot who gets himself
into a spin in an airliner made way too many mistakes long before that.
