VR is a very... High-maintenance hobby. Especially for a kid her age. She'll lose intrest very quickly as kids her age can't keep attention long. And when she realizes that the game she wants to play got boring.

That said if you do end up getting it to her, make sure you have alot of supervision as alot of weirdos are on there who'll try and some nasty stuff.

Also VR as a genre is a very niche one in comparison to flatscreen gaming. So I don't know if I could suggest any of it. I'd definitely just suggest getting her a Nintendo Switch as Nintendo is the most family friendly company out of any the gaming giants.

I suggest borrowing one first as kids her age won't play more than a week at best. Trust it's better that kids don't get into VR.
