When Rocksteady's Batman: Arkham Knight released back in 2015, it really felt like the end of an era. A trilogy of some of the best superhero video games of all time, accompanied by some great spinoffs and prequels developed by other studios, the Batman: Arkham universe had a great run on the whole. Though it received criticism at the time for its overabundance of Batmobile gameplay, Batman: Arkham Knight was a great swansong for the beloved series. But then Suicide Squad: Kill the Justice League reared its head.
