If computer guys can make super realistic 3d first person perspective games.. why dont they still make a system that takes a person and gives them all the sensory mechanisms including special glasses to view the virtual environment, a little thing that provides smells, a little feature that makes you feel stuff touching you…feel rain etc.. or whatever.

i mean 1. feel things or people touching you. feel the breeze 2. smell whatever virtual environment you are in. 3. see it as if you’re in it

and basically feel like you’re in it.
And i dont mean cheap little virtual systems that say it’s virtual when it’s only VISUALLY VIRTUAL but you dont feel anything else.

this question goes for a) any kind of dream like or realistic situation so that you are in a virutal world and interact with things and people ..b) or for virtual sx environments

if this exists already ,it must be really expensive and not very accessible. but it’s time to give it to the general public but not children
