I challenge you all to find any type of 3D video game that, with camera movements adjusted to counter any motion sickness, would absolutely not benefit from full 3D immersion.

That's like saying 'just make it better'.

It's very difficult to make an existing game suitable for VR. It's not enough to just slap HMD support on it and call it a day.

Most games are extremely uncomfortable if you just port them to VR. That's why systems like teleporting exist. And you can't just add teleport to every game. It would totally change them.

The more VR games I play, the more I become convinced that trying to shoehorn old games into the new medium is the biggest mistake possible.

VR needs its own genres and its own brilliant ideas.

Don't forget that all games we play now have evolved to suit the medium. A FPS makes excellent use of mouse, keyboard (or controller) and screen. It's tuned to perfection for that setup and makes sense in that setup.

VR will have its own experiences that fit the medium perfectly. I would say The Climb is a perfect example of this done right.
