Case has fascinated linguists for centuries without however revealing its most important secrets. This paper offers
operational explanations for case through language game experiments in which autonomous
agents describe real-world events to each other. The experiments demonstrate (a) why a language may develop a case system,
(b) how a population can self-organize a case system, and (c) why and
how an existing case system may take on new functions in a language.
