Are there any ingame actions that lead to a change in the ending of Bioshock: Infinite? Similar to how Bioshock 1 and 2 worked, where in 1, if you killed a certain number of Little Sisters or didn't kill any of them, it would significantly impact the story's ending.
Does the same thing apply here? Or is the ending the same every time, no matter what actions you take (ex. throwing ball at couple, picking a brooch, shooting certain people, etc.)
