As someone who has worked a bit with VR, I'm not convinced that there's much distinction between fonts or VR and fonts for any other medium.
But... If VR Fonts are indeed a 'thing', and they end up being important, then this domain is of course perfect.
So I'm thinking the best strategy for now is "hold".
IMHO this domain isn't a clear value play at this point. But it very well might be in the future. I think this is one of those wild card domains that kind of depends on where the technology goes, and how important the concept ends up becoming.
My 2 cents
