Definitely sounds like a VR project imho. The idea of working with blocks to build something sounds interesting and quite likely very worthwhile (even for someone like yourself who lets say comes up with more ideas than [insert-deity-here] on a weekly basis 
].
Also thinking about an idea for a VR game. But sadly don’t have the rig to support UE PCVR at the moment… Also really really gotta love how Godot just seems to run on a VR device out of the box (without all the bugs or pages of instructions for getting UE to work 
).
