Skyrim and Minecraft on the Switch and Fallout 4 in VR...
This and Skyrim are going to move a lot of units, I have no doubts.
2017 be a heck of a year
So not "easily" at all. Sounds borderline unplayable.
They could have easily done the following:
autojump like the mobile version
Lstick - move
clickLstick - sprint
face buttons to move your view (maybe even with a bit of gyro for good measure
plus/minus for crafting menu/ pause menu
L trigger place block
R trigger use/ dig
Not impossible, not the best way to play, but it would totally work
