From the Wushu Open text:
Traditional role-playing games also alienate themselves from action movies by segmenting time into rounds of only a few seconds. In the movies, you get to see characters trade a whole series of attacks, defenses, and counter-attacks before the camera cuts away. In role-playing games, players are usually limited to one action per round, and they only get enough time for one swing, punch, or pull of the trigger before the next player's turn. This takes the back-and-forth pacing that's essential for exciting fight scenes and stabs it straight through the heart!
In Wushu, players are encouraged to make as many attacks, leaps, dives, parries, and ripostes as they like before any dice are rolled. Each "round” is divided into two parts, which everyone completes at the same time. First, the group Describes the scene; this is the important part because their narration determines what actually happens in the game world. Then, they Resolve their dice rolls to see how well it all worked.
