Eurogamer writes: "Here's my impression of David Cage brainstorming ideas before making a game:
"Okay, it shall be set in a regular city, slightly in the future. Our character must get through his day, while becoming embroiled in a strange mystery. A peculiar girl is stuck in a tornado, and the player must rescue her before all the water in the world turns to stone. Aliens attack. At the end it rains cars."
While Heavy Rain stayed in reality, Omikron and Fahrenheit begin with a facsimile of a recognisable life, and then dive headfirst into a swimming pool of insane."
