Science usually ruins things, some time good things like beer, sweets, laziness, so this is one of the few times a study actually is beneficial, especially to game design. The study done by Gamasutra, used player feedback and biometric data to rate not only the most frightening games, but their most horrifying moments.
A victor was picked, but some of the study’s other conclusions were more interesting. For instance: The threat of combat was scarier than combat itself. Also, gore, while provocative, wasn’t particularly frightening. The game that understood those concepts the best? Well, that would be Dead Space 2, which took the brass ring over Condemned, Alan Wake and Resident Evil 5.
Even though Science has confirmed a winner, what would you classify as your scariest game.
