To Ian's question my sisters all have kids. Non of them are close to gamers. My youngest sister used to be a Nintendo gamer up to Wii she loved it her husband hated it so he basically bullied her into PC/Tablet gaming when he got her an iPad. As far as I know her kids do not have cell phones but when they do play games its on the iPad. Ages are the boy, oldest is 8, girl is 5 and youngest boy will be 3 this May. They don't have a game console in their home at the moment and no plans to, the last one they had was 360 and they sold it a while back.
My other sister has 4 of her own kids, her new husband had 3 kids previous and the oldest of new kids has a baby new born recently. Her kids have nothing in their home as he, the new dad, is anti-gaming all about the sports so when they are with mom no games allowed in the house period, except occasionally on the cellphone.
On weekends at their dad's house they have an Xbox 360 and a Wii and 3DS. He lets them play games all they want the break down is like this oldest boy is 11, he likes Xbox and 3DS, the oldest girl is 8 or 9 she is not into games at all, youngest boy is 6 or 7 somewhere in that area, he doesn't play games either except when I have the kids he plays NES with me. The youngest girl, she is mommies leech so she doesn't game and isn't likely to ever.
Kid we used to baby sit long time ago, she grew up on Nintendo games because thats what I had in my house and my sisters all babysat her and I did too from time to time she was good friend of the family. She just turned 16 and is a gamer girl all the way loves Nintendo and Playstation. She also has ipad and Cell phone games.
My Oldest nephew is 17 gonna be 18 soon, he loved Wii when he was younger now hates it he is all Xbox all the way even hates Playstation. He does not game on his phone or PC but he doesn't have a PC. His dad is a computer programmer and tried to push him into PC gaming that failed. Anecdotal for sure but its a start, probably as reliable as VGcharts if you want to go there.
Now when *I* am around these kids I try to get them into gaming. The boys will all play Ninja Turtle games or Mortal Kombat with me, usually classic ones arcade and that era. The girls, when I do have them the closest I can get to them gaming is Mario on NES, usually Mario 3 seems to be the only one they will even try, oddly enough the only other game she will try is Ninja gaiden she is amazingly good at it so she likes to brag. I haven't seen these kids in close to two years but will have them all next week was planning on introducing them to Wii U gaming then, Mario 3D World, if I find the time, since Mario Party 10 won't be out yet and I haven't even opened Nintendo Land yet. Since I am taking them to the big zoo in Omaha chances of gaming are very slim anyways.
Now to be fair my family has a strong anti-video game bias party due to well me being such a gamer they think its you know bad influence or whatever. Also most of my family are rednecks who like Nascar and fishing and everything else is a waste of time to them anyways.
