Batman Arkham Joker Story Ending Explained

Rocksteady's decision to lock the Arkhamverse into a trilogy and end it definitively with Batman: Arkham Knight has left the franchise with basically one Joker story left untold. The studio deliberately severed future storytelling possibilities over a decade ago, which frankly might be the worst thing that ever happened to the series—even worse than Suicide Squad: Kill the Justice League's disaster of a launch. That hard stop means any new Joker content would require breaking canon or retconning. It's a shame considering how much potential the villain still has in that universe.
