This game is, taken as a whole, fantastic. One of the best adventure games available. However, this point may not be obvious on the first playthrough. It's actually fairly difficult, which may drive some players to a walkthrough. That's unfortunate, because playing this game with a walkthrough is a terrible idea. The game's two strongest points are the story and the atmosphere. Both are fantastic, but excessive walkthrough use can ruin your understanding of the story. The game should be played with a mindset of truly trying to understand and solve the mystery. That will require reading and rereading the documents you find several times. But doing so is extremely enjoyable once you finally begin to grasp what's happening. If you get towards the end and feel that you have no idea who any of these people are or what's happening, you've missed a LOT. But putting the effort into exploring and understanding is extremely enjoyable.
