Very much more of the same, but it's another very well designed and polished action adventure with a cinematic plot and quality voice acting. All three are very similar, but that doesn't matter because all three are great.
Great Game. Not as good as 2 but better then 1. I did enjoy that there were no magic creators in this one. My recommendation is that if you have not played any of the Uncharted games and you have a PS3 you need to play 1 and 2 then play 3. You will not regret it!
