Yeah i think it could work if maybe they come out with two different games first the game with Damian & just make that one episodic & yes i don't think he should be Batman but its whatever on that subject, now the second one should be a sequel to Arkham Origins with an extremely massive Gotham city to explore, at least 6 islands, same as Arkham Knight we should get a drivable Batmobile, & like Oldschool said in the main post of this thread we should also have the option of using the Batjet. And the Batcave should be the same one that has been suggested in the main post of this thread or a Batvave that is similar to the one being suggested. So if they r going to do Damian in anyway then they should make his game more like the Batman Telltale game but if u r going to do an actual Batman game open world game then it should about Bruce Wayne as our Batman not a replacement Batman who will not make much sense anyway. I guess they r going to change Damians history around to fit him in as Batman cause that's the only way it would work. Well anyway that's my take on it & i fully believe Rocksteady & WB Montreal r working on a sequel to Origins.
