Unfortunately however it's set up, there is never enough adjustment for a lot of people and a surprising amount of people won't ever have good enough stereo vision for the effect to work.

Correct IPD in VR makes for a comfortable experience and objects being more accurately sized, but it won't stop it working if it is incorrect.

You're right it wouldn't stop anybody playing in VR, but I also don't think it would be such a straight forward change to change the VR game into a 3D one. I wouldn't be unhappy if it was included, I'm all for options. I guess I'm just sort of shocked at this point in time anyone would want to go back there.
