If a player is assigned the number 3 she must have 3 words in every sentence. Players that must speak in 10 word sentences become rather talkative characters. This is a good listening game. If the other players just wait for a player that is a word or two short, there is tremendous payoff. The one word player is asked to explain herself, or give directions.
All players have the same sentence length and that changes throughout the scene.
Players must decrease, or increase, the sentence count throughout the scene.
