We've done a significant amount of work, unifying the games and improving aspects of control and aiming. We worked on bringing U1 and U3 closer to U2, but we incorporated some global improvements such as reducing the dead zones, and making analogue aiming more responsive and precise across all three games. We also allow players to increase aiming sensitivity beyond the maximum values in the original PS3 versions. Uncharted: Drake's Fortune had the most drastic set of changes, such as including grenade control and functionality that more closely matches U2.
