I've played the Arkham series for the first time recently and this game is tied for first place with Arkham Knight for me. Story is easily best is the series. Characters are ok. Gameplay is improved over Arkham Asylum but nothing crazy. Map is so much better than Arkham Asylum. Side missions are good. Boss fights are better than Arkham Asylum but still not that great. Overall I really like this game and I recommend it.
