My kids were thrilled to get this and loved looking everything up - so detailed! BUT as soon as they put it to use they noticed mistakes. For example, the minifig you are supposed to get for completely a level is not the one listed in the book. And the stud amount for getting Jedi Status is also listed incorrectly. This was all in the first day of using the book, so Im guessing the mistakes are throughout. I would almost send it back, but I think it has lots of useful info too. This is our first Prima guide, so I wonder if these mistakes are common?
