From the information:
POP! is about people who love and have sex with balloons. There will be no balloons and no sex in this game, but keep love in your heart. Looners, as they often identify, are real people, and so are you and your players. Take care.
Players will spend an hour in Cyberspace, communicating through writing. Then, all the characters will meet in person, IRL, for half an hour. Then, play ends.
