Brothers, A tale of two sons. It is a three hour adventure. The controls are tricky at first, but once you wrap your hands and head around controlling the two protagonists, it is a beautifully told, heart wrenching story. Followed closely by Portal 1/2.
I've seen it, just never played it. It looks like Ico. Now as far as portal, that's a game I can play over and over. I do however have the VR Stories version on my HTC VIVE
