People play games to have fun, not to make the world a better place to live.
“People read books only for enjoyment, never to learn anything.”
We can just scratch off all those books — yes, entertaining books! — that we read because they introduce us to new things, give us a glimpse of different lives, teach us a little bit, challenge us, and so on.
“People look at pictures only because they are pretty.”
Oops, Picasso, toss that Guernica thing. Goya, quit doing those paintings about the Spanish Civil War.
“Movies are just entertainment, for fun, not to make the world a better place to live.”
Good, we can discard everything from All Quiet on the Western Front through Schindler’s List.
This is an inane statement; sorry to be so blunt, but… all media can be used for a wide variety of purposes. And fun and making the world better are not mutually incompatible. The sitcom Friends made the world a better place, in its small way, with constant messages throughout, even down to its annoyingly catchy theme song. Hell, even “fun” itself is making the world a better place in itself quite often.
To say that games cannot do whatever other media can do, that they are “just for fun” and have no other purpose, is to betray a profound contempt for games.
