documents: #Person1#: What can I do for you, sir?
  #Person2#: I'd like to choose one game for myself and one for my younger sister.
  #Person1#: What kind of games do you like?
  #Person2#: Big games of course.
  #Person1#: I see, but games are played in different ways. I'm wondering what type of games do you like to play?
  #Person2#: Type? I don't know, what do you have?
  #Person1#: Basically, there are 7 types of games
  #Person2#: Well, I am a beginner. I. . .
  #Person1#: Don't worry. Most male customers choose first person shooting, real time strategy, action or sports, while female customers prefer simulating, action or role playing. Shooting, action and sports games require flexible movements and real time strategy usually needs overall consideration.
  #Person2#: I like first person shooting and action more than other types of games.
  #Person1#: If so, counter Strike and Might & Magic are good alternatives. Counter Strike is one of the hottest shooting games and Might & Magic series are popular among girls because the game has attractive plot and interesting scenes.
  #Person2#: Oh, thanks a lot. Then, I will take the two.
  #Person1#: Do you want the latest editions? If your computer runs fast, I think the latest editions are better because although old editions are cheaper, they are less exciting and attractive.
  #Person2#: I will have the latest editions.
