Thanks to the likes of Samsung's Galaxy Gear (and the upcoming Project Morpheus from Sony), you don't need a PC to experience VR, but it's by far the most developed platform. Despite it not yet being a full retail product, anyone is free to buy an Oculus Rift DK2 and check out some VR games. Those range from full retail releases like Alien: Isolation and Elite: Dangerous, right through to weird and wonderful indie games like Affected and Radial-G over on share.oculus.com. And, if you partner the Oculus with a Leap Motion, you can even ditch the pad altogether and go for full-on motion-controlled immersion.
