Yes, yes, I know it's meant for children, but it still has the nearly constant sense of dread, abundance of scares, ever present ghosts and spooky locales you'd get in a horror game.

Sure games like Pac-Man have ghosts throughout their entire run, but the levels are so happy and colorful that there are no real scares or creepy atmosphere around, and Ghouls N Ghosts is more of a dark fantasy experience.

So, is Luigi's Mansion a horror game? Did I miss anything that'd disqualify it from the genre?
