You can feather the prop on a PT6 free-turbine engine and

this at idle or very low power settings. On a piston
engine, feathering the prop stops rotation, so the engine
quits.

On a PC game, the electrons stop flowing?

I wondered about that. In a turboprop the engine starts with the blades
feathered. However, I don't have the experience to comment on them.

As Jim said the PW PT6 engine has no physical connection between the power
section and the drive section. When you turn the prop by hand you are not
turning the engine. Some actually have a prop brake so you can stop the
prop with the engine running to be able to run the accessories (AC and
generator).

The Garret turbine engines are direct drive, they have a driveshaft between
the engine and drive section. When you turn the you are turning the engine.
These engines will not start in the feathered position.
