And thus we get VR games like Slenderman stalking you, on the streets of your home town! Or GTA 6 - Your City. ARK or Day Z, but set in actual Detroit. Oh, what amazing gaming possibilities this unlocks.

And hopefully, self driving cars and quadcopters and other drone robots can use a 3d model of a city, to better navigate the real world. How about teaching a self driving car, with the GTA 6 - Your City game?
