The second game seemed pretty well-received around here, so I figured we should probably have a topic for the sequel, which just released yesterday.
I'm about 4-5 hours in in Chapter 9, and I'm surprised at how oddly...slow and low-key the game has been so far. Whereas Uncharted 2 got going fairly quickly and then just bombarded the player with big cinematic moments and set pieces, Uncharted 3 seems almost subdued by comparison and more interested in character relationships and backstory. It reminds me of the first Uncharted in that regard, and honestly I don't know if that's a good thing. Uncharted is still probably the best franchise in gaming when it comes to cinematic storytelling, but it's never been its strongest when you're just wandering around environments doing minor platforming and solving puzzles (at least one of which was incredibly obtuse, and after seeing the solution I don't know how you were supposed to solve it with the scrap of info they give you). There have been a few pixel-hunting puzzles that were particularly annoying, since the game just flat-out stops until you figure them out.
The game is gorgeous, though, and the voice-acting and cinematics are as good as ever. There are some nice new gameplay additions that make the game more enjoyable (such as now being able to throw back grenades tossed at you and incorporating a vertical element into stealth), but nothing as game-changing as Uncharted 2's stealth and melee improvements. The game showcases the past and present relationship between Sully and Drake a LOT this time around, and it's very much welcomed. I just wish the plot would get on with it, because it's almost too deliberate.
Overall, a good game so far, but I don't think it's paced anywhere near as well as Uncharted 2 and the action sequences you do in it aren't as interesting or exciting. The level-design could also use some work (I've run into several stages so far obviously built for multiplayer and re-used as single-player locations).
