The stereoscopic panoramic videos that we're showing on Samsung VR are getting a lot of positive traction. It's exciting when you see creative types - whether from the music, film, or video industries - look at this stuff. The gears are turning in their head almost immediately about how they can use it as a new medium.
To the game code, the world is still just a tile map, but for rendering, each map was exported as a general-purpose 3D model, and the artists could then go through it and spend the polygons any way they liked, without the limits of line-of-constant-z software rasterization that we lived with on the mobile phones.
At its very core, virtual reality is about being freed from the limitations of actual reality. Carrying your virtual reality with you, and being able to jump into it whenever and wherever you want, qualitatively changes the experience for the better. Experiencing mobile VR is like when you first tried a decent desktop VR experience.
