As folks probably know from the oculus.com here, they are trying to "radically redefine[s] digital entertainment" and want you to "Immerse yourself in games or go inside your favorite movies. Time travel, space travel, or hang out with friends in VR." And while they claim "Endless worlds await," hardware can only be as good as the software running on it and once the platform arrives, there will be plenty of lesser forms of programs available that will cheapen the experience. I wouldn't be surprised if, even once developed, we can't often make the devices do what they are already fully capable of doing.
Remember from a couple years back, on motherboard.vice.com, where the claim was made that "'Ingress' Brings Virtual Reality MMOs Into Real Life?" What they had was essentially trying to leverage as much VR tech as could be had with a LARP (Live Action Roleplaying). They seem to have had some success and I love the "Ingress Report" up on their YouTube channel which helped make the whole affair a multi-media, multi-platform experience. Enjoy!
