When looking back at the long lifespan of the PlayStation 2, it's honestly staggering just how many games were released for the system. In fact, the PlayStation 2 became the home of over 4,000 titles, with games still being developed for the system even after the PlayStation 3 came out in 2006. Although this did mean that players had more than enough content to enjoy, it also resulted in a lot of games flying under the radar, especially when it came to the horror genre.
