"Wushu is a family of games based on the Wushu system designed by Dan Bayn.
Wushu runs on several principles. The first is the Principle of Narrative Truth. This means that whatever a player describes is exactly what happens. By doing so, Wushu can more closely emulate an over-the-top action movie style of play, since there are no penalties for difficult or flashy maneuvers. Counterbalancing the first principle is the second principle: the Veto. Anyone at the table, gamemaster or player, can veto any detail and ask the player to describe something different. This helps ensure that the tone and genre of the game is maintained at all times. Players can even use this mechanic to suggest alternatives to one another, which helps create a stronger shared-storytelling experience."
