One last thing: we're sticking with Fallout 3 and Fallout: New Vegas for this list. Whether it's a nod to a piece of classic literature, a carefully crafted mystery or just an irradiated monster, Fallout knows how to do horror better than some entire survival horror titles.
It makes sense that a game about the nuclear apocalypse would have its fair share of jump scares, but Fallout's always taken it to new heights. However, there's another, under-appreciated side of Fallout: horror. More importantly, the kitschy tone and humor are enough to keep the wastelands from being entirely depressing. Callbacks to an idealized post-war America are what give the series its unique feel, and its sci-fi elements are intentionally retrograde. Fallout is typically known for two things: massive, intricately detailed worlds and post-apocalyptic science fiction.
