IGN interviewed David Cage and he had something interesting to say about Detroit: Become Human. When asked about the length of the game David Cage responded “Well the game is going to be about eight to ten hours long, pretty much like Beyond and Heavy Rain”. He continued to iterate while the game will be that short it will have a lot of replay value in that game is heavily reliant on choices and the choices you make in the game impact your story. He recommends sticking with your choices on your first playthrough and then on subsequent ones, exploring how the different choices play out and change the experience.
Detroit: Become Human will be a PlayStation 4 exclusive. At this time there is no announced release date.
