I'm glad some of the puzzles are still puzzle like. One of my bigger annoyances with the Uncharted series is that they pretty much hold your hand on the puzzles. I really hate when I'm searching for possible treasures or looking around a room and one of the characters blurts out the damned answer to the puzzle when I haven't even got around to looking at it yet. Still happens in 3, but it's slightly less obvious sometimes.
