Closest thing to horror I ever played was Dead Rising, but it's a blast. For a while i played Costume Quest each year and I have the sequel, but for some reason battles lag on my computer. Since it relies so heavily on timed hits that's kind of very bad.

I usually liked to play games that had traditionally spooky parts in them. Big Boo's Haunt, Mad Monster Mansion, Pumpkin Zone (Mario Land 2), Pokémon Tower.
