The only thing that was "scary" about the first Resident Evil was the horrendous voice acting. I'm glad I never owned a PS1.
You
masters of lockpicking.
Granted, it scared the crap out of me the first and only time I actually sat down and played it. Then again, I was like... 12 or something.
Ah! I nearly forgot Fatal Frame/Project Zero 2: Crimson Butterfly. Overall, I think that is the scariest game that I've ever played. It really sets you on edge, and the FPS mode in the Xbox version just makes things more unnerving.
