Among the greatest PS games ever created.
The graphics aren't the best (the animation scenes are though), but it had beautiful, haunting music that I still love to this day.
The game is also a very dark one; some violence, dark music and themes.
Like Abe, it has complicated, clever gameplay that requires a lot of thought. And usually, you only have one chance to make your move.
If you want to play a good Playstation game, then buy this (if it's still available), and play it to your hearts content.
