For about six years, Rocksteady could seemingly do no wrong, delivering three incredible Batman: Arkham games and changing the superhero video game landscape forever. Though Batman: Arkham Knight wasn't quite the swansong that it should have been, it was still a great title and one that's probably only going to keep getting better with age. Rather than leave the series on a high note and move on to something completely new, Rocksteady has decided to return to the Arkhamverse. With Suicide Squad: Kill the Justice League, it's a decision that could be detrimental in the long run.
