I love horror games, but the 2 scariest games for me have to be Call of Cthulhu: Dark Corners of the Earth and (surprisingly) Dead Space 2 on Hard Core difficulty. I haven't had a thrill like I did being worried about dying and losing hours of progress in some time... Though I will admit the atmosphere and feel of DS2 was nowhere near as good as the original's. Where I found Silent Hill 2 to be an amazing game, I didn't find it to be very scary. Offsetting, yes, but where I felt uncomfortable, it never quite became scary for me. Silent Hill 3, where not as good as 2, was scarier to me. The Resident Evil remake for GameCube was also really well done. Fatal Frame (Project Zero for most of the world) would be scarier to me if I didn't get so annoyed with the camera controls at times, and Ammesia just never really clicked for me I guess, though I did still enjoy it.
