I've done a few hundred hours in military flight sims and the basic principle is the same. It is a simulator, not an replicator. You can't ever experience more than around 1g of accel but it is very easy to "fool" the body's otolith and vestibular systems (XYZ axis in inner ear for balance and rotation, and organs for sensing gravity and linear acceleration)

Once you're immersed in the simulated world, you do start to believe it. (whenever a student pilot crashed I would flinch!)

And oh yes I wantie!
