Hmmm... I don't understand the problem some people have with video games. I've been playing video games for like 20 years now and I've never been obese or stupid. Games do not make you any worse than books do, if you know what I mean. A neglected kid will turn into a retarded and obese reflection of parental failure whether he/she plays video games or not.
My brother is 10 years younger than me and since my father was always away for work, I had to be his father most of the time. In fact, I still have to be more often than not. I've taught him what my father taught me. I've disciplined him like my father disciplined me. I've also shared my entertainment with him : Video games. He plays them even more than I do and it sometimes makes me want to smack the back of his head and tell him to take a break. The thing is, he's kinda smarter than me now and he's more successful than I was at his age.
If playing video games were really so horrible that we must all avoid it like the plague, shouldn't they have made us (my brother and me) obese and retarded? Shouldn't we have been turned into delusional individuals who can't tell reality from games, as games are often claimed to cause?
Seriously, being a well advised and good parent is the only issue here. It's not like my brother and I are the only ones I can show you as examples. I have about 7 friends who play video games since as long as they can remember and they are quite normal people. A child turning into anything unpleasant is entirely about the lack of good parentage. Games or TV or whatever can not harm your child if you are being a proper parent.
Parents who do not agree with me, please do not take offense. I wouldn't dare judge anyone's parentage here, I'm just talking about what I know, from personal observation, to be facts.
