I just bought Torchlight (never played it before) for $3.99 at Half Price Books and finding it very fun (am now experiencing a “hang-over” from playing too long without eating/sleeping).
I don’t know that it’s a particularly creepy game (yes there are ghouls and ghosts and skeletons and blood), but there are some nice moments of anxiety. One type is the obvious: you never know when a horde of spiders is going to come crawling out of a bunch of surrounding grates, that sort of thing.
But another I just noticed, for me anyway, occurred on a level which takes place on what is sort of like a castle top. For the most part, all the terraces are bounded by fences or railings. But every now and then you get to cross a bridge that has no hand rails. I find this rather unsettling, even though it is impossible to jump off and hurt yourself, even if you try.
Maybe it is the contrast that makes this visceral: usually there ARE railings, so you pick your moments and take away the safety features here and there. If there were never any hand rails, then their lack would be ho-hum.
Okay! Here is a general principle to run by folks: If you want to make something really creepy, make the majority of it comforting and reassuring. Create lots of safety nets. Then, at key moments in the plot, remove them.
Using half-light or shadows for effect? Contrast this with bright lights. Using creepy sound effects? Contrast this with normal s/fx. Scary music? contrast with at least episodes of more neutral or positive energies.
