Inspirisles, and Inclusivity
Inspirisles is an all ages RPG, with a focus on storytelling, empathy, and cooperation. Its secondary purpose is to help teach you Sign Language.
Now I could leave it at that, but that would do the game a great disservice. It is as creative and well designed as any system, pulling narrative inspiration from Arthurian legend and mythology. It focuses on collaboration, world-building, and teen-adventures in the style of YA novels and 80s classics like The Neverending Story, Labyrinth, and The Lion, the Witch, and the Wardrobe.
