Sims have their place. I picked a friend just after he went through a
"sim" session, (He was training in a new type, 737 I think)

He was a MESS! They had piled several failures on him, he had to
change his clothes, he was soaked, and actually shaking a bit, and
his voice was unsteady. Maybe a sim, but what they put him through
was "real" enough! (he passed)

Probably two factors that brought on the sweat factor (and realism).

A. It probably was a full motion sim (or sim where he sat in it rather
then in front of a computer)

B. He had a job riding on the outcome

Much different then sitting in front of a computer monitor PLAYING MSFS
