If VR was going to be a big success, there would be a killer demo for the Oculus Rift by now. There isn't. "The Chair"[1] is considered one of the best demos. Whatever. GTA V in VR is pretty good, but that's because GTA V is pretty good without VR.
I've not used a VR headset before, but I've heard the games that provide the most immersive VR experience (at the moment at least) are 'cockpit'-based games such as Elite Dangerous. There seems to be some recognition of this from Oculus, as they're bundling EVE: Valkyrie with the CV1: https://www.oculus.com/en-us/rift/#eve-valkyrie
We aren't talking about today, we're talking about the near future. Nor are we talking about games, but other uses beyond gaming. The Occulus is akin to the iPhone 1, in a few years it'll appear clunky and outdated but it's certainly the first step in consumer quality VR.
