The reason I own a PS3.
Plus: Lush scenery, great combat system, excellent storyline, and a great set of characters that a person can get right into. The treasure collecting aspect is pretty cool and it has a lot of Prince of Persia-esque platforming.
Cover system is pretty good.
Minus: Occaisionally you just can't get Drake to take cover behind what you want him to. Game is definitely easy no matter what difficulty you play as, life is regenerating like in Gears of War. Sometimes the game doesn't detect you catching a ledge when it should so you watch yourself die a couple of times.
