Video games are a waste of a man's time and unlike cinema was morally evil from the very beginning. So yes I call any man who spends a moment of his time playing video games a boy-child and not a man. I used to play that crap myself until I "grew-up" and my healthy body and healthy mind has thanked me profusely for giving that crap up.
This response, on the other hand, lacks a properly Catholic moderation and is somewhat wanting in common sense.
"Morally evil from the beginning?" How was "Pong" any more (or less) inherently evil than Edison's early vignettes of dancing Turks and trains pulling into stations?
A video game - so long as it is not sinful in content in itself (i.e. excessively, realistically violent, immoral, vulgar, etc.) is like any other game: morally neutral. A man spending "a moment of time" (i.e. a moderate and short amount of time that does not interfere with his duties) playing Tetris, or Pac Man, or Asteroids is no less a man and no more morally corrupt than a man who spends a short amount of time playing Pinochle, or Sudoku, or Backgammon, or even one of the many sports you have frequently lauded in the past.
If we seek to have a Catholic work ethic - and not the Protestant work ethic that pervades insidiously in anglophone cultures - then we must recognize the right of every person to rest and leisure in moderate amounts. Leisurely pastimes that excercise the body (like the sports which you encourage participation in) are perfectly fine and legitimate, as are ones which exercise the mind and dexterity, like board and card games and, yes, simple, morally neutral video game of the kind referred to above.
Can video games be a waste of time and an occasion of sin? Yes, of course, absolutely; but so can Pinochle, Sudoku, Baseball, Rugby, etc... "Everything in moderation," as VCR rightly and succinctly put it. As for children, because they often show a predilection for becoming addicted to video games, I would recommend greatly restricting the time they are allowed to play (and, it goes without saying, the kind of games they are permitted to play).
