My son loves these books because there is bound to be a truck, train, plane or car on almost every page. I enjoy them because I remember reading the books and playing the game as a kid. And they are not as repetitive as some of the other children's books... you can always find something new to point to on each page.
My husband got a kick out of these books when he asked my son where the phone was. Rather than point to the rotary phone (which my son has never seen in his life), he thought for a bit and then pointed to a blue rectangular block. Well, yes, that was the closest thing to a smartphone on the page!
What "mistakes" have your children made that are not actually mistakes at all, just a generation gap?
