PS store has GOY edition for 15.99 {37 in game} this is one of my all time favourite games, if you fancy a challenge and don't mind dying once or twice {Cough...} you will love this. Think I have completed the game about 8 times and still go back and play it now. Happy to jump in and help out if anyone gets it and fancies some co-op and the expansion "The old Hunters" is bloody huge, nearly as big as the game.
I will say if you have a short fuse and have a tendency to rage this game is not for you ^^. Absolute bloody bargain!
