Sure, he killed a buncha bad guys later, but Luke Skywalker wasn't always a badass Jedi. He spends much of the first film wandering around like a useless dork, which is exactly the kind of Luke Sywalker this new VR demo will have you simulate.
Using an Oculus Rift and a couple of motion controllers, Sixense has whipped up this demo giving you a choice of lightsabers then pitting you against a training droid.
It won't be the kind of thing you'll likely end up having in the home. But if a smart arcade/bar works out how to get one working, keep it clean and rent it out, then we're talking.
Well, that and talk with Disney's lawyers.
