The blaming video games/television for killing a child's imagination based on anecdotal evidence has to stop. I'd like to see some real studies on the topic, but I doubt anybody could accurately measure creativity for such a study anyway. The poster at Kotaku indicates that all of the kids in his daughter's class who watch TV/play video games/skip breakfast (as if he knows what these kids are doing all the time at home???) are much less imaginative than his daughter...
In reality, some kids have always been more creative than others, since before the invention of media. Hell, ancient Greeks continued inventing story after story about the same characters just like those kids writing scooby-doo fan fic for English class do. I would presume that controlled access to video games and television could possibly be just as beneficial to a child's creativity as it could be detrimental, assuming the child was taught to understand the creative process that went into developing those cartoons and characters, and encouraged to make their own cartoons or TV shows in a similar way.
I have just as much anecdotal evidence about growing up with my friends, and in my experience some of the most creative kids were the ones who watched Saturday morning cartoons and played video games regularly. They were the guys that ended up dungeon master for our RPGs, created a radio drama (with original characters) on our high school radio station, started a comedy/folk band, and studied acting, sound design, and computer animation in collage. Meanwhile the kids who were never allowed to own a video game system, well one of them is a grad student in the field of technical math... successful, yes. creative? not in the slightest. I know math people can be creative (I like to think I am) but this kid is not in the slightest
based on my observations, I could stand up and proclaim that games are a gift to creativity for children, aping the poster's opposition, but I know my friends did a lot more than play video games while growing up. Thus I'd like to think media exposure for a child can be beneficial, but only under the proper prescription
