Yup. I was talking about the one in which personal memories can be played. So many new concepts and theories in here. I'll take some time to go through them. The VR thing you're talking about is kinda similar to the the technology of Animus in Assasins Creed game where the character experiences the memories of his ancestors. Only in your case you're talking about watching the entire planet's history. If they have got this idea for a game long ago, it could be possible that the technology exists or people are trying to build it.
