My eight year old daughter loves stories and was drawn to the cute artwork of this game. It's basically a choose your own adventure story with occasional events (called tests in game) that require you to roll dice to defeat the bad guys or achieve a goal. Overall, the mechanics of this test system are pretty straight-forward and certainly easy enough for kids - in fact, I'd say this game would be perfectly suited for kids under the 6+ age recommendation. It took us about an hour to learn the game and play through both booklets so if you want a shorter adventure than this is your game. I gave it only three stars because it falls short in a couple places. First, I'd dock it a star because there were many passages of play where the players aren't given a choice, so you're just reading a story rather than actually making your own. Second, I'd dock it another star for the underwhelming "custom book" they advertise at multiple points throughout the game. Basically, you record the choices you make during the game and then can go to their website to create a custom book (as a PDF) by entering your choices. However, the book is nothing more than disjointed cut and paste paragraphs (each with their own title) and some clipart so it feels like a disjointed highlights section rather than a story. Also, you have to enter your character's name and gender when you are creating the book and despite putting my daughter's gender as a girl, the created book only refers to her character as "he" in a multitude of places. Given how much the book was hyped in the game, my daughter was really disappointed with it.
Edit: for clarification, the website lists this as 10+ but that's for the "Guardian" (parent role) whereas the on-box age for the "Dreamer" (child's role) is 6+.
