If you still haven't figured out why the Oculus Rift sells for a solid $200 less than HTC's Vive, let this be the final word: it's the motion controllers. According to a display in a GAME store in the UK (found by our very own Nick Summers), Oculus' virtual reality motion controllers will retail for £190, or just over $200 after deducting local UK taxes. That's expensive, but not at all unexpected -- if that price holds across the pond, it puts the cost of a room-scale Oculus Rift kit on equal ground with HTC's $800 Vive.
