I haven't been following vr much, but those examples look terrible. Maybe they could port freelancer over. Is it just going to be low res 3d with some kinect like functionality? There must be more. Just not seeing it.
Both of those examples are technology demonstrations.
Virtuix Omni is the treadmill device, but they have a couple of small games to show it off.
The toybox demo though is honestly one of the most amazing things of done in VR. Ignore the graphics, that's not what toybox is.
The special thing about that demo is the social aspect of the game.
We were playing together as if we were standing next to each other, but the Oculus employee was in a completly different room.
It's not really a game. its again a technology demo.
There are several games out there that are coming for VR, many of them visually stunning. Take a look for CCP's EVE:Valkyrie for a good example (which is coming with rift pre-orders, btw). porting games to VR doesn't work well at all. Needs to be build from the start with VR in mind to work properly.
VR games will in general be less visually impressive than the top level AAA titles for standard pc gaming. The 90fps minimum for VR will dictate that games for VR will need to be less graphically demanding.
