what's the scariest game you've ever played?

(this is all platforms, not just wii)

personally, mine's this old nancy drew game for the pc that i played when i was little, and it creeped the shit out of me.

Well it was late at night and I was playing Dead Rising Chop Till You Drop when this one boss attacked his motive for his Insanity was something about it wasn't fun anymore. Anyway so after I killed him he dropped his chainsaws (in which he was wielding as weapons)and fell right smack on top of them and as he was being sawed to death he was laughing manically I had nightmares that he would show up.

Super Gouls And Ghost (SNES) That game still scare me to this very day.
