This game gave me nightmares!
No, not really.
But you have to admit those Prefects scare the living daylights out of you.
It's all quiet, you're sneaking around and think you've got to the door then suddenly DUN DUN DUN 10 POINTS FROM GRYFFINDOR DUN DUN DUN!
I have to wonder about those with weak hearts who may have played this game because I know everytime it happened to me I actually jumped.
And as for any small children playing it...
The Prefects stalk me in my nightmares :O
