I hadn’t realised the new VR devices were so buttonfree (not a Pokémon). Virtuality had quite a few, if I remember correctly. The PSVR uses two Move controllers doesn’t it? Don’t they have lots each?

I think the problem with “not enough buttons” or even “the wrong sort of buttons” here is more “how do I play my traditional games on it?”, which of course is not the point: you don’t.
