With things like this, I guess eventually fewer and fewer will want to just passively sit and watch the films. Much more interesting to get into the world and test all the "what-ifs" that linear story does not allow, but sufficient AI could provide for. What if Luke never left Tatooine with Obi-Wan? What if he joined Jabba's gang and became a smuggler instead, while rebellion was still on same path as it was? Would Wedge have blown the first Deathstar instead?

What will it take, a few motion detectors in the room, a VR treadmill and a HMD for the player?

Noticed that too, it is why I haven't been into gaming lately. For a linear story with only game being "aim the pixels to hit other pixels", might as well watch a film.

But I think that after graphics are near-perfect and VR experience is good, nonlinearity in the story and speech-recognizing AI capable of believable dialogue will be next challenges.

I always thought gaming was about testing/observing what you would do. And movies were about observing/considering what others may think or do. I think both are valid art. It's not so much about the technology, but the way we experience them that makes the forms different.

Like a mentor of mine always said. "You can't learn shit with your mouth open."
