VR Zone in an Arcade created by Bandai Namco in Tokyo that was set up last year. If you ever get the chance to go you should take full advantage of the fact that $40 (¥4,400) will get you a four ticket pass for the day so you and three friends can basically hang out in the place having VR fights. One of the big attractions that has been getting attention the past couple days is the inclusion of a Mario Kart themed ride.
The game has four VR systems hooked into driving simulators shaped like go-carts to simulate what it would be like to drive as one of the characters in the race. Right now the game is basic compared to the actual Mario Kart 8 the designs are based on—you can only race as Mario, Luigi, Peach, and Yoshi, with a limited amount of weapons that includes turtles shells, hammers, and bananas. You snag items by reaching out to them as they hang from balloons and use your own hand to throw, drop, or guide them as to how you wish to use them.
Below is some footage of a guy playing as Luigi as he races against his friends and two CPU opponents in Wario and Bowser. Next time I'm in Japan, I know what I'm doing!
