My 4 year old loves this game. He plays it for hours and he can now say his planets in order from the closet to the sun. Very educational and he has had it for a while and is not bored with it yet.
Of the three games my then 4-year old son received last Christmas (Wall-E, Ratatouille and Cars), Ratatouille is the favourite, Wall-E gets played almost as often, and Cars not very often. Several of the Wall-E games get played, and overall, the purchase was not a disappointment.
