Had some company over last night and was showing off the PSVR to them. Their daughter (can't recall her age, but she's just starting 3rd grade) wanted to check out the deep-sea dive demo in VR Worlds. WITH the shark. I explained to her folks what the demo was, that it's not violent or anything, but the shark can be pretty damn scary in VR for grown-ass adults, let alone a kid who can barely wear the helmet. Her mom explained to her what it was, and that the shark would seem really real and RIGHT THERE IN THE ROOM and everything, but she insisted she could handle it, she was cool, it's just a game (she's a whip-smart kid, btw, really an amazing little monkey).
So I queue it up for her, and she plays it, all ooh-ing and ahh-ing at the scenery, standing, looking all around her, reaching out for the fish, really getting into it (last night was all my guests' first VR experience, and everyone loved it).
Then the shark shows up.
If you've seen the demo, the shark shows up in the distance, gradually getting closer, swimming around your cage, checking you out, and you finally get a sense of how big the fucker is. Then it suddenly attacks the cage.
She shrieked like, well, like a little girl. The whole time. We asked if she wanted to stop, but she said no, all the while doing that high-pitched shriek that should have broken all the glasses in the house. When it was over, she took off the helmet, all red-faced and flustered, looked at me accusatorily and said, "Why didn't you tell me it would be scary!"
