I love Silent Hill.
As a franchise it wavers in quality, but when it hits its stride it provides an experience that cannot be fully matched in any other form of media. The psychological narrative of even the worst entry is attempting more than entire genres of gaming.
Here is Climax Studios discussing how Silent Hill: Shattered Memories learns the psychological preferences of a player, and then subverts them.
When working on my upcoming interactive comic (Pixelton: The Helmet of Infinite Win) I realized that I’d created an interactive experience that had very little interactivity. The ability for a piece of art to react to your fears, hopes, and desires is why I started writing this book. So, a great deal of time has been spent finding ways to give a more immersive and personal experience to the reader.
The goal here, as seen in Silent Hill above, is that the reader is clueless to the customization taking place. It is seamless. But once the trick is revealed to them it has an even more awe inspiring result. There was a trick – and it was under your nose the whole time.
