Grimm (role-playing game)

The current version is a standalone game using the Linear D6 system.

The Linear D6 version is a significant expansion of the original material, including a more fully developed setting, a monster manual and game mechanics, all of which were previously provided by the core D20 System rule books.

Linear D6 is unusual in that it deliberately limits randomness having characters perform at their ability level 2/3 of the time.

The original version was part of Fantasy Flight Games Horizon open-ended miniature Dungeons & Dragons campaign settings, making of use the D20 System under the Open Game Licence.

The game provides new core classes which enable players to take on role of children lost in this strange and terrifying realm.
