Arkham city is my childhood and it's really nostalgic to me. Batman Arkham Knight is second.
Joker is and always will be batman's arch nemesis. Batman is somewhat scared of joker because of how insane the joker is and batman knows what he's capable of doing. That's why joker is one of the villains that batman is most concerned about. Even some of the other villains are afraid of the joker.
Nightwing and Harley were a couple at one point I think and if not they would make a good couple.
I also thought that batman escaped somehow and is using fear toxin to fight crime now.
Darkseid as well
With all my respect
Post arkham origins
I also agree on you for Kevin Conroy he's just so good at what he does with batman arkham asylum, city, and knight and roger craig Smith in arkham origins was also very good.
