This thread is so reassuring! At the moment my dd11 is mindlessly obliterating her entire Minecraft world by filling everything with TNT and blowing it up. (And no, she's not normally so destructive.) But it's so mindless, I can't believe this is what a gifted kid would choose to do with her time. I guess I had more choices to do unsupervised things outside when I was a kid -- and I doubt that they were very "intellectual" either!
