One of the main reasons I liked F3 was because I found it exceptionally creepy. I always thought of it more as a survival horror game then an RPG adventure game (or whatever you'd call it).
The parts I liked the most were the areas where the survival horror element was intentionally played up, like in the Dunwich building with it's subtle scripted events and most of Point Lookout.
Unfortunately, places like this were few and far between in F3. New Vegas looks awesome, but I haven't seen anything yet that looks particularly scary yet (I mean like the examples I pointed out)
So is anybody else hoping there are more Dunwich-type places in New Vegas?
I totally am, for me even when I first started playing F3, I thought the metro tunnels were pretty creepy, the way they made the ghouls act, but I hope they come up with something new to add a different element of of scariness..
The other thing I hope they add is the handcrafted locations and all of the dev placed little easter eggs all across the wast.. One of my favorite things in F3 was finding the corpses and skeletons in various states, it really went a long way to paint a picture of how desperate things were for some folks when they died, and I was really intrigued by all of that, I hope it returns..
