Grimm (role-playing game)

Grimm is a role-playing game, released by Fantasy Flight Games as part of their Horizon open-ended miniature Dungeons & Dragons campaign settings, making of use the D20 System under the Open Game Licence. A supplement to D&D that introduces a new setting based on the fairytales of the brothers Grimm. Albeit a twisted version of those, the correlation between the realm of Grimm and the original fairytales is in many ways comparable to the correlation of White Wolf's World of Darkness to the our world. The game provides new core classes which enable player to take on the role of children lost in this strange and terrifying realm.

Fantasy Flight Games recently released a full, non-d20 version of Grimm.
