A few months ago Thomas Grip, co-founder of Frictional Games, the developers behind Amnesia: The Dark Descent, wrote a blog post about the ten ways horror games can evolve. Grip makes a lot of good points, but the first one that stands out to me the most because it almost never happens in video games is the idea of establishing a sense of normality:
In most games the player usually starts out in some strange and not very normal situation…However, much of the good horror in other media starts of very mundane. They build on having the audience strongly relating to what is taking place and being able to draw close parallels to their own lives. For horror games this would mean to establish a very familiar situation and then slowly introduce the horror there. The goal is for the terror to not just be inside the game’s virtual world, but to reach into the real as well. (“10 Ways to Evolve Horror Games”, In the Games of Madness, 26 April 2012)
Then, as if right on cue, Telltale Games released The Walking Dead, which does just that.
