In the first category I tend to think of games like "Shiver" and "Phantasmat", as well as the first two "Ravenhearst" games. In the second...a lot of the "Asylum"-type games such as "Twisted Lands 2" and the latest "Escape from Ravenhearst". Some (like the new "Dorian Gray Syndrome" and "Sacra Terra") have elements of both categories. I admit that I have a soft spot for the more "eerie" ones, though I've enjoyed several of the others as well, especially if there is a good storyline involved.
So what do the rest of my D&E friends think? Am I splitting hairs? Is there really a difference?
