Dude you need to get the virt-a-mate demo. This game might get close to xstory real quick and with creator access you are able to customize a lot without even leaving the game.
Seems like the dev stole my wishlist from this forum

It has a building block system where you can use primitives to construct new stuff. Although its in a desperate early stage one can see where this might going. The current Version is more like a tech demo - but hell yeah!
Atm all the ingame Sliders are a pain in the ass, nearby impossible to get exact small values but i think meshedvr wil implement a PT Filter for inputs and will also use exponential sliders.
