Right,
Just completed Uncharted2 on my 60GB PS3 in about 7 hrs [in 2 days]. If you want a mix between a puzzle game and Assassins Creed then here you go.
The game is ridiculously difficult; I (re)check-pointed 121 times! I did about half the game on Medium difficulty and had to turn it down to Easy on about Chapter 25, I think. Half the deaths were do to him jumping to far out of cover and flying off the cliff.
The bonus features on the game seem to only be unlocked when you have completed it once, slightly annoying but I probably will do it again. I completed all the MGS games more then... 7 times so, not to much trouble.
I would recommend it to all the you sensible PS3 users out there.
The hardest bit is the monastery, particularly when you're stuck in the small building with enemies advancing over the bridge (before you enter the big monastery grounds).
Still, I completed the game on hard, got every SP achievement, and bought that fancy art book, I like it that much.
I got most of the Skins and the strange block shaded trailer.
