head to head
Heavy Rain asks more than Ken Follett's The Pillars of the Earth, and the gap is execution.

Execution · Light / Casual
Branching interactive thriller where QTE choices decide who survives the Origami Killer case.

Optimization · Light / Casual
An interactive novel that tests narrative attention more than any game skill.

Heavy Rain leans clearly harder on execution.
