Other than you don't have airplanes, big birds, loose balloons and other
assorted objects appearing out of nowhere, the aircraft isn't bouncing
around in turbulance while you try to maintain attitude and altitude,
there are no other people in the aircraft trying to talk to you,
there is a pause button so you can take a leak anytime you need to,
and there are no real world consequences to any of your actions, it is
just like the real thing.

Most of these things have no influence on ATC communication.
