Wow, the graphics look amazingly beautiful! The art and concept seem similar to the Breath of the Wild game, and I know the youtube commenter made some comparisons between that game and Zelda games which I can see why. Most importantly, you have me SOLD on the music because I am completely in love with Nier:Automata music and the music of Nostos just sounds so amazing as well.
Too bad I don't have any VR systems so I'm not too versed in the gameplay or variety of games available right now, but I'd say if they can pull off that game, it'd be a big step forward from the small variety of VR games I am acquainted with.
