I personally think that the game would have been massively better and have loads more replay value if there was a New Game+ feature. You would retain all of your skills and weapons, but it would unlock more premium style ones like The Shredder. You would face better equipped pirates at the start that do more damage, but you do more damage as well.
And the hostile wildlife can take out down in two hits if you are not careful... I really wish that something like this was in the game! The hardest difficulty setting was not really all that hard. It was kinda like Heroic in Halo.
Would you have liked end game content like this?

NG+ doesn't belong to anybody people. It's been around since the 90's. Hell, it was even in Dark Souls before Arkham City or Borderlands 2.
