I don't limit dd anyway, but def would if she stayed up late, or skipped homework etc.
She has various consoles and limits herself, very rarely plays during week but if she does she only plays when homework is all done and is very rigid about turning it off at 7pm.
iPads can be for so much more than single player games, they can be an ebook reader, they can be used for programming, they can be used for board games too, and a great amount of homework is online for dd and I lads are used a lot in school so when I see a child on an ipad I don't always assume that it's a video game.
Video games are not always a bad thing, there's some brilliant games that build skills that a great for everyday life, and I've said on a few threads recently, it's a valid hobby.
It's fine that people don't "get" gaming just like I dont get people watching soaps, or train spotting, or knitting, or baking. If a dh is ignoring a family as he's playing in Xbox then it's the dh that's the problem not the console. I think it's similar for a child, so if you have a child who is acting out, it's probably not the gaming that's the cause, it'll be parents who are not not teaching manners, not interacting with the DC. A child losing at a board game will be angry at losing a video game, they've not been taught you can't win everything and/or have everything their own way. I'm assuming the DC play age appropriate games, but again, if they are playing violent sexual themed games, it's not the games fault that adults have chosen to give it to a child, as the game is not intended for under 18s, and parents who buy adult games for their underage DC can't really complain about the content. There's no excuse as even a non gaming parent can look up a game in YouTube or wherever now and see what's what in gaming.
Was talking to dd yesterday about a few threads on here and she said it's funny because she's never heard any other hobby be blamed for someone's behaviour. If someone's out of the home fishing all the time and shirking responsibilities at home, then it's the dh that's criticised, not fishing, if someone gets engrossed in a book or knitting pattern, and doesn't respond to a question or something, then they are not called rude usually, but it's never knitting or reading or criticised. Both at she can be sat reading a physical book at a family party and people will comment on how well she's behaving, amusing herself while the adults talk, but if she's sat reading the very same book on a tablet, then she's being antisocial and it's a shame kids can't put them down for two minutes and take part in conversations etc etc.
I've never read a discussion saying my wife spends too much time knitting on an evening, she never looks up and sometimes she doesn't respond when I ask her if she wants a cuppa, and then everyone discusses the evils of knitting :)
I do think some children have issues with gaming, I do think some kids play way too much, I do think some kids are playing inappropriate content and I do thinks there's a problems with some children not being able to switch off from them, but a lot of the time, it's the parents who haven't set limits, who've bought the inappropriate games and who've not dealt with issues as they've arose. (Not all parents, not all children, but some)
I have a friend who often complains her 11 year old son kicks off when iPad is removed in a night , so she doesn't remove it, and he plays into early hours and watches porn, and she complains that he spends all day on it and has a struggle to get him to do homework. It's not the tablet that's the problem, it's the parenting. She's not dealing with the tantrums and she's not setting limits and not blocking the porn, she blames the tablet, the network provider etc and it's built up from the little things like laughing at him when he threw a controller in a mood when losing at five, from giving more than the agreed time because he wanted "one last go" etc
