King Wen's Tower

From the introduction:

This is a fictional re-telling of the end of the kingdoms of China and the formation of the Qin empire. Play involves scenes of culture, warfare and intrigue, where each player jostles to avoid annihilation for one more round. These are freeform scenes of play using prepared scenes and characters. After each round, one kingdom is conqured by Qin. Epic moments of their their domination are described, with glory or humiliation. Those eliminated take on new characters—generals, scholars and laborers of Qin — to help blot out the other kingdoms who remain.
