The following video of a TED talk is about a game developed for Microsoft Xbox with Kinect controller. The characters in the game are AI characters. The player has to interact with the character by playing, talking etc with the characters. At the end of the game, the developers say that, no two characters will be the same. Very interesting. This is nice mixture of both AI & Kinect controller.
In the video that author says that people did not believe when there was a video release of the game. I agree that it is really hard to believe. He gives a live demo of it in the TED talk.
