Any game with a large focus on the surreal. Art, music, writting, or philosophy that is bizarre or with little internal logic and reality that seems off, unhinged, or dreamlike.
Surrealist works feature the element of surprise, unexpected juxtapositions, and non sequitur; however many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost with the works being an artifact.
Surrealism developed out of the Dada activities during World War I and the most important center of the movement was Paris. From the 1920s onward, the movement spread around the globe, eventually affecting the visual arts, literature, film, and music of many countries and languages, as well as political thought and practice, philosophy, and social theory.
