Oh boy, I didn't even notice until I read your comment!
Nvm I see it now
Why is that? I don’t see any problems with this particular name. Valve index and oculus rift aren’t that amazing either.
The name is Relativty, which is one 'i' off from the normal spelling of relativity.
It's even more confusing for non native speakers.
It's more searchable?
No, it will just get auto-corrected. Removing a letter from a word as a brand name is dumb; it is no different than parents naming their kid a normal name with stupid spelling and thinking they are original/creative.
"RelativityVR" or similar would arguably be equally good for search, clearer purpose/context from the get-go, and much easier to communicate, vs " 'Relativity', but without second 'I' " ...
