Been playing Uncharted 3 and 2 is definitely better but still a very good game. I think I'm only about half way through but the level designs aren't that great and that was my suspicion when it was first announced the story was focused on Arabia.
I felt the same about God Of War III. Sony seems to fumble a little when it comes to the third game in a series while on the other hand Microsoft seems to fumble in the second game. i thought the Halo 2 and Gears Of War 2 campaigns sucked while the 3rd were great.
