Depends on what you want to experience for the Full VR Presence Interactive experience that can fully manipulate your Brain and cognitive functions (like a drug), yes you do need a VR Headset, else your presence and immersion factor will be very limited and way less addictive.
Also "VAM is no Game" i'ts rather a "creative experience of another kind".
If you just want to experience it from the outside like your normal flat Animated 3D experience on a 2D Display in Real 3D Space.
Such as you experience these now watching it

then the answer would be nope, but if you want to feel like being there and experience it from the outside as a observer or even being him or her actively then the answer would be yes, it's impossible to fake the Brain into believing this without the headset on a 2D Display in 3D Space, unless you aren't heavily drugged already while watching it
