Kmeme blog says that Google will make its imagery available to game developers: "A game company will be able to license the entirety of the real world’s roads and all the surrounding areas from Google. The data will be streamed over the network from Google’s servers, where it is displayed seamlessly with the actual game elements.
The physical road surface will be mapped at centimeter resolution, every bump and rise accurately depicted. The visuals along the route will be in 3D and super high resolution, you could see the spots on a ladybug if you slowed down enough. And playback during the game will be silky smooth thanks to copious bandwidth and massive amounts of local hardware to warp the imagery in response to each subtle change in eye position."
