Certain scenes having a VR component could be cool. I think of some of the lunch scenes from Rewrite - particularly the ones in the courtyard where it might fun to be able to switch from a “reading mode” to a “scene mode” where they make you feel more enveloped in the moment with VR. Done well, having VR scenes kind of take the place of special CGs while most of the game stays flat feels viable, though really easy to mess up.
Or they could make Mappy more gimmicky by making those segments VR. Which is what I kind of think will happen.
