Absolutely not. It's very much a science in their development, to bring about the addiction. To bring about the excitement and exhilaration, the sound effects, the movement and things like that. There are games that we could call non-addictive, but they aren't selling, so they're not being developed. It's a funny sort of phenomenon. To develop a very successful game, it's always got to be addictive.
