I realized something of what makes Mirror’s Edge so cool: you can finally move completely freely around the map.   It’s not that parkour needs to be added to every game– though the more the better.  It’s that you are no longer defeated by a chain link fence or a chest-high wall.  Or even a knee-high wall as in Jade Empire.

Not cool at all however: the DLC doesn’t work if you bought the game over Steam.  Sigh.  Might as well go back and finish Fallout 3.
