The collectors edition of this game is the perfect showcase for a game that has quite frankly the highest production values that I've ever encountered.
While somewhat lacking in originality of control and trailing behind the likes of Bioshock in terms of immersion, the story that is told is well polished reminding me of an episode of Supernatural. Additionally every facet has clearly benefited from careful playtesting and balancing to deliver constant challenge without ever feeling unfair. I have yet to find a single glitch in this game after two playthroughs.
I would thoroughly recommend this game, and in particular the collectors edition as this gets you the soundtrack which features some truly excellent original songs.
