The communication game “Are you a Werewolf?“can be next-generation standard problem for artificial intelligence which comes after Chess, Go or Shogi and so on. Our goal is to find “How can people enjoy playing the games with AI”. For the purpose, we employ the collective intelligence method to develop AI which can play Werewolf. In this paper, we introduce the AIWolf project and game platform which designed to play Werewolf by artificial intelligence agents. Number of participated agents are 38, and 15 of them became finalists. Also, we describe about the First AIWolf contest and analyze the result of the contest. From the analysis, we found that the winner agent has significantly higher winning rate. Also, we found the relationships between roles and winning rates which are important information to develop agents.

The cut scenes by computer graphics have become used for the video games with the advances of information technology, and then, the creators brought in a new technique so-called QTE (Quick Time Event) which makes players to put some buttons while watching the cut scenes. In this study, players’ reaction time and understanding of the context of the movies during QTE were investigated by psychological experiment using the system like QTE. The results showed that the novice players take much time to put the buttons if the interval between tasks is long and the sign of the button mark is small. In this case, all players' understanding of the cut scenes dropped slightly.
