Summary: the older kid has enjoyed this for a few years, and introduced younger sibling to it. Now younger sibling is very happy to have own copy. If your kid has an interest in dinos/fossils, they will likely enjoy. I have not played it, but sounds like you are challenged to find fossils, fight dinos and can level up and achieve all sorts of dinos. 15yo has done all this, but still plays the game on occasion or is game of choice when playing with younger sib.
Summary: I got this for my 6 yr old son that loves dinosaurs. He plays the crud out of this thing. His older brother wants it too along with one of his girl cousins:) It requires some reading and he is challenged by the amount of reading at times (sometimes skipping it) and he needs some direction due to this, but he still can't stop playing it.
