As players, we now have no objection to exploring a world we simply cannot significantly influence. 'I know the 'C' word and associated fear along using a desire to follow 'nature wisdom' is partly to blame for the emotional approach. One final gripe - the final third of the action is 100% carbon copied through the previous game - I'll prevent the spoilers, but if you've played Uncharted 2, you will know what I mean if you see it.
