Gamification: Meaningful Choice
Heavy Rain. That was the name of the game that first made me understand that meaningful choices could take a game to new levels of immersiveness.
If you have never heard of it, Heavy Rain was a PS3 exclusive in 2010 from game makers Quantic Dream. You played the roles of several people through a convoluted mystery. There was the father who had lost his son, the private eye, the reporter and the FBI agent all linked to the mysterious Origami Killer. As the story unfolds, you have to decide how each character acts, how they handle conversations and what choices they make.
