Grimm is a fantasy-type setting for a world of imagination that resembles the classic fairy-tales of old. You play the part of a kid caught in this world, trying to make your way home, completing adventures and quests along the way.
It's a fascinating book, with a unique game-play system and a rich world to explore. The rating would have been 5 star, except for the price; either buy the PDF or the book, but not both: I suggest that you buy the book, unless you really like to read things from the computer screen.
All in all, a great purchase and a great game -- seasoned game players will find it interesting, beginners will find it informative. Grimm is a must-have for your collection.
