Resident Evil is take a pretty sharp turn to a more PT-ish horror style, and it seems to work to good effect. It is only a short little demo with a couple of multiple paths, but it sets up an interesting tone for what to expect in the future.
Aside from Resident Evil 4, I never really got into any other game from the series. I also did not think that most of those games were or were suppose to be scary at all, since it always felt to be that it was a series of action movies with a large amounts of suspense and dark rooms. This new game seems to truly go all the way in the horror direction, which might be for the better, considering how much people seem to dislike the most recent Resident Evil titles.
