3. Moderate. Even though it is easier then the first 2 games there were a few part's that gave me moderate problems. The ship yard and In the desert before you rescue sully. The rest of the trophies were easy to get and I even thought the treasures were a little easier to find. I did have to use the videos to find the last 35 I needed. Found 65 on my own which is much more then what I found on my own in Uncharted 2.
