Good Responses keep it up!

Something about 3 just gets me in the most. The set pieces were my favorite for the series by far (ship physics were making me drool), the convoy was incredible, and the story had more Sully than 2 which is always good. The finale was also the best in the series by far as well. The ND Uncharted games, though every one has been fantastic, have gotten better with each installment for me.

I have to give it to Uncharted 2. It's just a tiny bit better than Uncharted 3. JUST A BIT!

This. Multiplayer and Coop is better in U3 ofcourse. 

Uncharted 2 absolutely blew me away. I loved it to death. It's one of the best games I have ever played. Uncharted 3 was a huge disappointment. The story, set pieces, and shooting were all mediocre.

UC3 easily

Uncharted 2 has better singleplayer and characters, while Uncharted 3 has better multiplayer and graphics and refined gameplay mechanics. I prefer Uncharted 2, though I haven't played Drake's Fortune or Golden Abyss yet.

funny because I thought 3 was better in specifically all those areas.  The shooting seemed basically the same to me.  The set peices I definitely preffered in 3 though.
