Looks like another back-door attack on computer gaming. "Knowing all the techniques with which we tried to bring about addiction..." You mean like making it entertaining--fun to play--like that? When his 3 & 4-year-old daughters learn how to read and get a few years older and begin to comprehend the world around them--then maybe they might be able to comprehend something about his games--maybe. Along with TV, books, and movies, and all of the things their creators do to make them "addicting."
People need to get over this "addicting" phobia--air is addictive, food is addictive; entertaining TV, books, and movies are addictive. Reading is addictive, as I'm sure his daughters will appreciate one day in the future, when they can read and become literate in English, of course.
Some people even think the NYT is addictive, if you can believe that...;)
It is well known that I cannot err--and so, if you should happen across an error in anything I have written you can be absolutely sure that *I* did not write it!...;)
