This Oculus Rift experience is like Tron. Only instead of being stuck inside an arcade game you're stuck inside the mind of a Sonic fan (or Sonic meme artist).
I'm probably most impressed with the amount of research that went into building all these models. It's like a zoo for Sanic and running fast.
