A lot of Uncharted 2's charm comes from its script and storytelling, which is much better this time as well; the banter remains fast and furious, and the characters are even more sympathetic/intriguing. I don't want to spoil the experience for you, but I'll point out that the conversations between Nathan and Flynn, now rank as my favorite "dudes talking shop in a videogame." Rather than discuss specific plot details, all I'll say is that Uncharted 2 is a whirlwind adventure centering on Nathan's search for the mythical city of Shangri-La. Some of the things that you'll do -- in a without-context-to-remain-spoiler-free manner -- during his 11-ish hour (on Normal difficulty) journey include:
Team up with two other characters in a crazy shootout against multiple hordes of bad dudes.
Take on a mercenary toting a minigun on top of a speeding train.
Leap from a flaming speeding truck onto a non-flaming speeding truck.
Run through a besieged town while being pursued by a tank.
Shoot at a bad guy grappling with one of your buddies while sliding down a collapsing floor.
I'm not 100% certain when it happened. I think it's when I had Nathan Drake atop a building in a war-torn Nepalese city, cornered and being fired upon by a helicopter, engaged in a fist fight with the screen slowly draining of color, snapping my enemy's neck and quickly rolling into cover to reload my grenade launcher only to turn and fire upon the chopper one last time as I watched it crash and explode.
I think this is when I realized that Uncharted 2: Among Thieves was the best single-player game I have ever played!
How can you rate the online 10/10. Given that you omitted to even mention it in your admittedly short review, I can't help but wonder if you actually played it at all.
By the way your quote about when you realized this was the best single player experience is a direct quote from adam sessler from Xplay. But I mean if u feel the same way thats cool, maybe you should quote it.
