What game is too terrifying to finish for you?

Mine is Silent Hill 3. Its subject matter revolves around the fears of a teenage girl, like death of a parent, puberty, unwanted pregnancy (with a demon fetus, no less), mirrors (THAT ROOM shivers), and stalkers. The atmosphere is so oppressive and I cant play the game without having something else playing in the background, its that horrifying. I managed to finish Silent Hill 2 last year, which was like conquering my own fears. One day, I'll finish SH3. One day.
