> It sounds awesome to think about being in VR and being in the FPS

Yes. This is one of the things that leads to the counterintuitive truth that if you want a fully immersive and fun game (defining "immersive" as "the player is no longer aware that the game world is not their actual reality), you don't actually want too much realism.

What you want is an "effortlessness" -- the ability for the player to trigger an action without effort or conscious thought.
