Mine got into it aged 8 and 9 and at least one of them still plays occasionally. She's 14 now. No regrets, it’s been good for them. It’s 21st century Lego. They create homes and worlds and share them with their friends, play competitive building games online, play team games of all sorts. It seems like a great online play space with a strong creative streak in it.

I think it's a much better use of their time than watching cartoons. Although I did get my girls into Sailor Moon and the modern run of My Little Pony. I'm a strong believer in giving kids a grounding in the Classics.
