For me when i first played the resident evil 3 on PS, (this was the first game of the series i played) i was very scared by watching the intro, and as i started to play, i was shaking, i played it till my first encounter with nemesis, and i jump a feet above my bed, he killed me, i turn the game off, and didn't played it for whole week. Than i started again and beat it in 3 days. After that i played all games of RE series. Ever since than nothing like that happen to me, and i am not scared of games any more.
Ive played Silent Hill 1,2,3,4.
Alone in the dark on PS,. it was the most scary game i ever played.
Suffering on PC....etc.
Now i kinda like horror games, especially RE4.
