It's one of the most amazing games I have played to date. The lore, the story and the writing is just done amazingly well. The game-play, level design and world exploration is just freaking exceptional. I would suggest playing at the "Give Me a Challenge" difficulty as it makes the game even more fun than it already is. A must play!

P.S. Kudos to Santa Monica Studios & Sony for porting this so well for PC.
