This requires a PC. There is an upcoming Facebook "all-in-one" HMD called the "Oculus Quest" but it only has the computational power of an Xbox 360 (and with VR rendering requirements, the effective performance is considerably less). And the PS4 does have a "PSVR" add-on. It has some great games and a decent HMD, but just has really poor tracking and motion controls. If you find a good deal or something you might want to try picking one up, but talk with me about simulator sickness first. There's a specific procedure that most people must use to adapt and none of the VR "platforms" give you any guidance other than a very abstract "comfort level". You need a lot of computational power to run PCVR games smoothly. I can't recommend anything less than an i5 6600 and a gtx 1060 6GB, though people claim to get away with less. Basically you're rendering the scene twice every frame at an extremely high resolution and wider FOV (~110 now, probably 135 to 150 with Valve's next hmd, and there's currently an ultra enthusiast focused HMD that has a 200d fov--the Pimax). There are also a ton of unexpected things that increase the computational load for VR related to textures, LOD, tracking, vsync, etc etc. Until recently you needed to do all of this at about 90fps to avoid discomfort but there are now reprojection techniques that sort of interpolate between frames (oversimplifying here) so sub-90 doesn't look so bad now (but has occasional artifacts). And stuttering of any sort is a terrible feeling in VR so devs need to be extra careful. There are issues you will notice in VR that you wouldn't notice on a flat screen, and there are things that can make you sick in VR that can be difficult to attribute a cause to. And it still looks really pixelated right now. It was pretty rough at the initial launch of consumer VR but I have to say that things have come a long way--most devs are aware of the sources of discomfort now (well, UE4 and Unity framework devs have helped a lot of course). In addition, there are VR specific hardware optimizations in 10-series and up GPUs that can reduce the rendering load. In order to achieve higher resolutions we will need eyetracking assisted "foveated rendering" where you essentially only render the portion of the screen in focus (actually quite small) at the target resolution and then render the periphery at lower and lower resolutions. From what I've read the peripheral degradation is unnoticeable but could cut the current computational load in half. Eyetracking also has a lot of other applications for convenient user input, social interaction, and interesting game design (e.g. imagine if horror devs knew exactly where you were looking and could detect saccades--between which you are effectively blind). Functional eyetracking has been available with very expensive add-ons over the past few years, but in the not too distant future it *could* be coming to consumer VR headsets (perhaps if we're really lucky the upcoming Valve HMD). To give you an idea of how well it works, recently I was reading the impressions of a journalist using such a system integrated into a VR headset and they were able to effortlessly trace the perimeter of a cube located some distance away (as confirmed with an eyetracking reticle) and then, using an eyetracking enabled head cannon, proceed to repeatedly blast that cube into the sky until it was the size of a single pixel. As I alluded to before, I still think it will be some time (5 years?) before VR is appropriate for a good chunk of PC gamers, even "hard core" ones. Everyone is blown away by VR initially--there is a sort of "honeymoon phase" after you first try it, but thereafter the discomforts really start to wear on you. There is a high "cost" to just using VR. After a month or so, most people would rather just play a flat game comfortably on a monitor. It is a strange thing: I have several friends that I've gotten into VR and some can't get enough of it while others just can't be bothered to put on the headset. The latter group never seems to regret the games I coax them into playing, but the "cost" of usage seems to dissuade them from independently using it. Only enthusiasts (like myself) are really willing to tolerate those costs--e.g. people that are burned out on flat games, that love experimenting or hacking around, that enjoy playing with cutting edge tech, etc etc. The discomforts are mostly visual but the weight and head-mounting mechanism also play into that. For this reason, while there is a lot of noise about the cost (price) of VR systems I think subsidized hardware (or compromised specifications) at this point would be a waste of money. Once the major issues are ironed out though (probably culminating with variable focus) I can see the VR percentage on Steam gradually creeping up. We're currently just under 1% right now. I'm actually a bit worried that Valve making a new HMD and bundling it with "HLVR" (which is what all of the leaks indicate, potentially releasing this year) will get your average PC gamer interested in VR too early on. But pressure from Facebook/Oculus may be forcing them to release something
