Never played it and never will. I'm 46 and those types of games just don't appeal to me. The kids are brilliant and pick it up easily. But at what cost? Health wise we are regressing badly in this country.
Depends on your point of view I suppose but I would rather see kids out playing and getting themselves dirty and building up a good immune system. Nowadays it's all ant-bacterial this and anti-biotics that. The amount of bugs that circulate nowadays is unbelievable.
Someone will no doubt come out with ah but being outside isn't safe etc. Personally I feel that the media are responsible for scaremongering parents into not wanting their kids to go out and these games are the ideal antidote.
I find it a bit sad though that kids don't have the same freedom that we had. In fact we probably had too much.
