Just opened this game and played it for the last 2 hours and I must say I was highly disappointed.  The mechanics from NG2 and NG3 are night and day.  I don't know which is more frustrating: fighting several helicopters with just a bow or while you're fighting enemies, you have a few enemies shooting at you on balconies.  Itagaki, or however you spell it, you made a terrible mistake leaving your game in someone else hands.
