Crushing was definitely FAR easier on Uncharted 2 than it was Uncharted mainly because there seemed to be a lot less cover in the #1 opposed to #2. There didn't seem to be a huge increase in difficulty at any point in Uncharted 2 either unlike Uncharted which threw in a S.W.A.T team with the sniper rifles and SPAS with little cover and flanking on both sides throughout the last third of the game. Uncharted 2 had the whole mythical creatures thing going on but except the three that you first fight I can't remember another point you were forced to fight them head on.
