Clearly very Rock Band inspired, but compared to the plastic guitar games of yesteryear I really don't know if this one will be able to capture the feeling of precision and mastery that you would get with those games. Beat Saber and others make it work by having the input be something large and designed for VR, whereas it seems like this relies on too much precision to be fun when it's up to motion controls.
It's a shame that Rock Band VR never really worked, and that having a controller attachment to an old Guitar Hero guitar just isn't viable. I'd love to play Clone Hero in VR like this.
