Just finished this game last night and I have to say, if you own a ps3 its is ESSENTIAL that you purchase this one.

Everything about the game is so well polished.
Great story,
seamless, exploring/gunplay/beatem up.
A good long single player campaign (too many games can be finished within a few hours by experienced gamers ), uncharted 2 took me around the 20 hours mark.
The only game so far to utilize 100% of the ps3 power, and it really shows, breath taking scenery, deep crisp detail, and stunning visual effects.
Voice and model acting is top notch, found myself laughing out loud at many of the cutscenes due to the quick wit of the main character.

all in all, a very enjoyable game. (yet to even get round to the multiplayer)

So incase you've been on a different planet for a while heres the trailer.
