I'm in 3D Grafix world!!!
Of all the games mentioned above only call of cthulu was able to really scare , it was also a difficult game to complete with an interesting story . Anyway the game graphics for todays standard is outdated .Call of Cthulhu for the feel. Fear 1/2 is lame (wrt horror, other things are cool)
Then try a brief session of four hours or so of F.E.A.R 2 from third stage at 11 P.M to 3 A.M alone at home switch of your room's lights put on a good 5.1 channel gaming headphones take its volume to last bearable level change your PC monitor with your 42" full HD LCD TV five feet away from you and set LCD's mid point at your strait eye sight level set full eye candy on from the game's graphics settings. Although it will not frighten you but you can feel your heart beat going up a little.
