Uncharted 2 was far better. I was speaking to a friend about this the other day, he says he got bored of Uncharted 1, but loved Uncharted 2. There is so much more variety, and the stealth aspects really add to the gameplay, especially in the some of the tougher fights towards the end of the game. The story is far more involving as well, with a broader range of characters and a wider range of locales doesn't hurt
