I was playing revelations last night from 12am-2am, lights off, headphones in, it's not suppose to be a 'scary' game as the 11 years old child anticipated it to be, more like horror type/experience.as alrady mentioned, sound plays an important factor on these games. try playing with headphones and lights off. it really puts you in the game
also. im 21 and ive been scared of games. dead space and dead space 2, using turtle beach on almost max volume and lights off. now that IS scary
