SpyParty is a spy game about human behavior, performance, perception, and deception. While most espionage games have you spend your time shooting stuff, blowing stuff up, and driving fast, SpyParty has you hide in plain sight, deceive your opponent, and detect subtle behavioral tells to achieve your objectives.
Unlike the suave and confident spies you might find in films or books, most spies in spy games are more like super powered commandos--more Rambo than James Bond. By contrast, SpyParty is a new and quite different game about the more interesting and deeper aspects of being a spy.
You should know who the spy is and why the spy is the spy.
Hints vary in quality and how much they reveal, but are mostly meant to help. Gender reveals the gender of the spy, so it should be about a 50% cut in possible suspects each time (casts were selected randomly).
