One thing I have to point out is some things can only be done in virtual reality maybe this game could work without it but some things(games etc) can ONLY work in vr and I thing Hideo Kojima said this best quote
"IGN: Do you like VR?
Kojima: I love VR! I would play it now but atm I have Death Stranding.
IGN: Out of the VR content so far, anything you particularly liked?
Kojima: Nothing yet that I've particularly liked, which is what makes me want to work on a VR game myself (laugh). I think it's a shame more people are not trying new ways to bring out ppl's emotions. While film is good for what film can do, games do what film can't, and VR again does it different. VR can make users feel in ways that was previously not possible, this is huge, yet no one is doing this! They see VR as an extension of traditional games, but I think it is not. (延長線上, lit: extension of a straight line.)
IGN: You mean they should be focusing on things that can only be expressed in VR, and not just rehash traditional games?
Kojima: If I said what they should do, then people will just copy that thing, so I won't say it here (laugh). But I do think it's a real shame, here's a hint. 120 years ago, the Lumière brothers produced motion picture. This was done by flipping a screen encapsulated in a frame repeatedly to create the illusion of moving pictures. This culture of a screen encapsulated in a frame continued a 100 something years. And with it evolved the challenge of how to move people to laugh, to cry, to feel fear, by manipulating what's in the frame.
Kojima: But now with VR, there's no frame. There's no frame, and it's interactive. This opens up possibilities. You can do things that was previously impossible because of this frame. I would love to explore this area while no one is at it yet.
"
TLDR "But now with VR, there's no frame."(That is the short version)
