While there are plenty of horror games out there, these are the best for second-time play due to their high replay value.
Horror adventure games are rarely known for their replayability, though some are good enough to break that assumption. It's like a horror movie that shakes you to the core but makes you want to watch it again in the future. The excitement and fear is enough to make you want to relive it. That mixture of fear and anticipation made the second outing all the sweeter.
