Actually, this game deserves 4 of 5 in my opinion: its a good stealth game, but with some small disadvantages - checkpoint-based save system, some traps are really annoying... again, in my opinion: I clearly understand that other people wouldn't find all of those difficult or bothersome. The main reason why I rate this game 3/5 is the absence of Special Edition content here, on GOG. Not only it is the additional optional chapter, but also there are specific costumes and options for playing the main game. Therefore, the game here is stripped down to the vanilla experience.
