My kids loved "Google Cardboard", especially that solar system app they heavily promoted for it, where you could "fly" around space and look at the planets in 3d. So I'm pretty sure they'll like the Big N's new "Labo VR" set too-- in fact, I think I'll throw that into the budget for April right now.

If it sells enough, I wonder if someone will make a head strap for it, and add support to it in actual games? The system already has separate-hand wireless controllers and a headphone jack, so it's got all the bases covered. Of course, the graphics would be absurdly low-res to be able to render high fps scenes for each eye given the Switch's meager power, but that'd just give the games more charm imo.
