Steven Spielberg was at the launch:
"The video games industry has not allowed us the opportunity to cry, because we were too busy putting our adrenalin rush into the controller, or wherever we swing our arm with a Wii controller to get a result," he said.
"Because of that, there is no room for a video game to break your heart. We now have a little more room to be a little more emotional with Natal technology than we did before."
I found Steven Spielberg's comments slightly disturbing, but I suppose making video games that really upset people may be something that games designers want? It could be another design principle for pervasive media people to think about; not just how addictive we make experiences, but how much we manipulate people's emotions.
