Nothing can truly prepare you for the experience that is Journey.  Part meditation on the nature of solitude and part demonstration of the effects we all have on the world around us, Journey is proof positive that sometimes less is in deed more.  Journey has a control scheme that is easy to follow and yet, somehow, complex in a fascinating sort of way.  The puzzles are not incredibly difficult but I would argue that they remain perfect for the game as it is.  The visuals are captivating, arresting and are worthy of a host of other superlatives.  Finally, enough can not be said about the score.  It is clear to see why it's Grammy nominated and proof that an amazing score can evoke as much emotion as anything.  Do yourself a favor and pick up Journey, but be prepared for an experience that is incredibly rewarding and yet hard to describe.
