"_Games get serious_

I also remember Stephen Jay Gould's article on the movie Jurassic Park and technology in The New York Review of Books. (Dinomania http://www.nybooks.com/articles/2483 ) which points out that games, entertainment, recreation, push important technological change and help in the construction of interesting thought models.
