PPG wrote, "Heavy Rain is a unique experience that places you in control of four main characters that must solve the case of the Origami Killer. Unlike previous games before it, Heavy Rain's game play focuses on quicktime events instead of standard free-roaming controls for combat, communication, and investigating locations.
The quicktime event was originally pioneered by Don Bluth in 1983 with his arcade laserdisc smash-hit Dragon's Lair. Unfortunately, games like Dragon's Lair were linear and limited the player to a sparse number of moves, giving the illusion of control. Technology was the biggest limitation back in 1983, but the vision lived on."
