Nutcracker Prince uses a fusion of D20 OGL mechanics, Advanced Dungeons & Dragons 2nd Edition proficiency data and magic items, and novel rules. The game is set in a realm with three distinct locations and characters can travel between them. Each realm is distinctive and has some of its own rules. The setting has a medieval feel but also incorporates Renaissance elements, much fairy tale mythology, and black-powder firearms.
