Let me start by saying I am only ok with this because it's an excuse for me to get VR as well. I have a computer that can play VR games and a PS4 with its camera. I am looking for a system that will fit a 7 year old and play the stuff out today. I'm unsure about compatibility but Most vr games he's exposed to is via YouTube. Between PSVR, Occultus, and Vive what is the best choice?
