Fallon's "play by play" sort of brought up a good point which is why I think a lot of people were turned off by it. How many times did he say "ok, this isn't you" "I didn't do that, this isn't me" "Ok, now this is you"? Too often, in this section, you're taken out of control. I've joked with my brother how Uncharted 3 will probably have something "CRAZAY!" happen every two steps like a floor gives out, ceiling falls down, stair crumbles underfoot, a door pushes in on you etc.. all this just trying to get to a second floor of an unoccupied building. It may be a little jarring.
Imagine if last E3's footage had a cutscene trigger whenever debris fell from above everytime the helicopter shot at the building showing Drake dodge to the side.
