The Witcher is an action role-playing hack and slash video game based on the book series of the same name by Polish author Andrzej Sapkowski. The Witcher takes place in a medieval fantasy world and follows the story of Geralt, one of a few remaining "witchers" – traveling monster hunters for hire, gifted with unnatural powers. The game's system of "moral choices" as part of the storyline was noted for its time-delayed consequences and lack of black-and-white morality.
