Okay, okay, you got me...
I refuse to play Luigi's Mansion at any time other than night because the first time i played it was at night when I was little, and it scared me so much. That's pretty much the only reason I was ever scared of the dark. of course, when I play it now, I don't find it too frightening, but when i play it at night, sometimes I can still get that good (scary) feeling.
