From my post in the official Uncharted 2 thread:

Pros

• Grenade controls were greatly improved, THANK YOU!
• Fun story that doesn’t let up one bit the whole way through
• Shooting and platforming is a lot of fun
• Awesome set pieces like the building falling or the train
• The game looks incredible, probably the best game out right now.
• Fight layout is much better
• While stealth is easy to break, it’s a nice addition
• Melee is much better this time around
• I love that you don’t just walk into an area and 20 enemies appear, because of stealth you can now choose how the encounter starts

Cons

• Guardians were stupid.  They take so much damage to kill and you don’t even know if you’re hurting them.  The only time I wasn’t confused if I was doing the right thing was when I had the portable gatlin gun. 
• Every encounter with multiple guardians sucked.  The worst was the one where three of them with grenades come out and rape you constantly.  If I didn’t know that was the next to last chapter I would have quit right there.
• The final boss sucked, it was just too long.  They could have shortened by half and it probably would have been fun.  Also, the tracking grenades are stupid.  I could take the most random squirreliest path and a grenade would still end up at my foot.
• The whole last chapter before the boss was just a giant let down.
• There were many times in the game where I just didn’t see the path I was supposed to take and just kind of wandered around jumping on everything until I found what I was supposed to find.
• This is a problem I had with the first game in that since the game has the system where you automatically make jumps, you don’t have a good gauge on what jumps you can and can’t make.  I died countless times because something looks like a jump I’ve made before but since that was where I wasn’t supposed to go I just died.  There was one instance where I dropped down into a building like 6 feet and died.  Bullshit.
• Getting in and out of cover was still a little wonky
• Camera many times would be annoying
• Sometimes jumping from one handhold to another handhold was just hard.
• Puzzles were again a let down.  They aren’t really a puzzle since the game painfully pushes the answer in your face and if you for some reason take your time it just flat out tells you the answer.  Why are they even there?  They only hurt the great pacing.
• In general, all bosses were just bad (train guy, helicopters, guardians, last boss)
• Picking up weapons-- fuck you whoever implemented this.  I don't know how many times I died because what started out me trying to pick up ammo turns into standing there juggling guns because a shotgun and a micromachine gun both happened to land right by it.

The main issues I had with the game was just fighting with the controls, camera, and figuring out where to go next which is sadly the same issues I had with the first one (though I got lost MUCH more in this one).  It’s a shame because there’s so much good to this game that they didn’t fix those things.

The end of the game just wasn’t that great sadly.  I was pretty excited to play through the first Uncharted several times in order to try and get the platinum, I don’t know if I ever want to play Uncharted 2 single player again.

And I thought about it for a minute, I think the worst offender of the not-obvious thing award had to have been the part where you hang off a sign to shoot the boards off a door and then enemies flow in and you fight them while hanging off the sign.

So Chloe tells me to get the boards off the other side of the door.  I look around the area and I see a clear path I can take to get other there so I jump on the sign and then I try to jump onto the destination...except I can't get off the sign.

I sit there and mess around on that sign until the game eventually just tells me to shoot the boards from the sign.  That is the fucking dumbest things I've ever seen in a game.  You don't just randomly change the rules so you can set up the next encounter.  If you want me on the sign, fine, but don't put it in a place where I should be able to jump right to where I think I'm supposed to be going and don't make it low enough so that I should be able to drop on the ground.

There's no reason to make that so I dick around for a 5 minutes thinking the game was glitched.  I was actually getting up to reset the console when the hint prompt came up.

=========================

Overall, I give it a 9.2. 

It was riding high in the 9.5 range before the final few chapters but the final part of the game lowered the score a lot for me.

10

Holy shit at SFIV!

OT:

9.8/10. My personal favourite game this generation.

+Stunning graphics
+Incredible story
+Some of the greatest environments I have ever seen
+The previous mixed with fantastic physics makes for a phenomenal combination.
+Pretty much every problem with the original was fixed.
+Great musical score
+New characters provide a great contrast.
+Multiplayer is addictive.
+Loads of replay value to attain the Platinum, which is hard enough to take time, but easy enough such that you'll keep going.
+More weapons
+More cover/aiming options.
+Better melée system.

-While the game appears extremely open, it forces you down quite a narrow path.
-Final boss battle is lame...again.

One of the greatest games I've ever played, overall.

I agree with pretty much everything you said about the Guardians.

But the Shambala chapters were in my opinion the best part of the game.

9.5

9.8

Great SP, good script, good voice acting, fantastic gameplay and amazing cinematic moments
Amazing engine, fantastic visuals, superior sound and music
Great coop and really solid MP

Slightly weak ending and a few inevitable clipping issues keep it from 10, but only just!
GOTY for me.

Could this be the top ranked game? I can't wait to get this on Christmas.

It's a 10.

Without a doubt - 9.9/10

One fault with the game itself, the final boss.

Apart from that, it had nothing at all i could give it negative points for.

I really didn't mind the guardians, what I did was I saved my grenades and would throw em at them in 2-4 at a time. That usually killed one of them and I would take the crossbow to kill them. The crossbow kills em real nice.
