Fatal Frame II. Why? Because it scared the freaking bajesus outta me, yet I couldn't stop playing it. Seriously, I'd be going thru a creepy house and suddenly a crab walking ghost with it's head backwards would pop up on the screen and I'd scream my head off. Trying to sleep at night, my heart would be pounding, I'd be seeing ghosts in my head, and I'd have to steal my son's nightlight. My husband took the game away finally and said I wasn't allowed to play it anymore after he found me sleeping with every light in the house on and the kids in bed with me.
