It’s hard to explain what using a virtual reality device is like. This new Valve trailer featuring the HTC Vive shows what it’s like to play games using a VR headset. A lot of the games and experiences shown in the video come with the Vive for free including The Lab, Hover Junkers, Everest VR, Tilt Brush, to name a few. One of the things that sets the Vive apart from the Oculus Rift and PlayStation VR is it allows for room-scale and it comes with motion controllers. This allows you to physically walk around in a virtual space, giving a different kind of immersive experience.
