Makes you sweat!
The best thing about this game is that it doesn't use the "jump from around the corner" technique to scare you, but it's about atmosphere around you. Everything - the music, buildings, characters, even the smallest things in the game - all that is really creepy and scary. Keeps you on the edge of the seat.
Another thing I liked about this game isd that it combines quest and action. You don't just walk around killing everything that moves - you also gotta use your head and solve some puzzles.
Well, we'll just have to wait and see what the 5th part of the game got for us...
