This is a portion of a review of Flight Simulator X, using a pair of 400$ VR glasses with head tracking. Everything this new Virtual Boy could be:
"Then the game started.
I've picked a lot of nits, and at this stage I've been wrestling with drivers and trying to put a shirt over my head to block out incoming light. I'm kind of cranky that way. All of that annoyance was gone, as I found myself inside the cockpit. Like, inside it. I look down and see the instrument panel. I look left and see out the window. I look up and see the rivets holding the metal plates of the plane together. I took off, looked out the right window over the empty seat, and banked hard so I could see the ocean beneath me. Amazing. The sense of flight and actually being there is almost overwhelming."

There's no question it would be an amazing tech to use on the Wii and something else unique on the platform that neither Microsoft or Sony could offer so fast.
