 The company's planning department looked at the arcade industry and noticed that Japanese video arcades were primarily populated by young couples; Namco and Kounoe decided on making a large-scale arcade machine that could be enjoyed by these couples, primarily men.Looking for inspiration, Kounoe noticed the surge in popularity of buddy-cop movies in Japan, such as "CHiPS" and "Police Story"; he decided to make the game a homage to these films, as he felt it would make it easy for players to become engaged with a familiar setting.
