9+? Pfft more like 6+. While the game can be challenging at times, it's still a great adventure. The story is about aliens stealing natural recourses from earth, and it's Chibi's job to get them back. The game takes place in the 7 continents, each world being a different continent. Consumerism is a big part of the game, since you can collect snacks, from Pez to Utz cheese curls. If you are gonna buy, buy soon. The amiibo bundle sells quick.
