Hi
My 11 yr old has had nintendogs for the past 6 months. at first she was on it all the time- now she plays on it every so often- I think the novelty of having cute little dogs having to be fed and played with has worn off. I have a 4 1/2 year old boy and he's had a go on my daughter's nintendogs and lost interest in about 5 mins. I think perhaps if you can get it in a BOGOF offer or preowned at a cheaper price maybe it'd be worth it but I wouldn't buy it for my youngest. Hope this helps a bit.
