Next game should feature Deathstroke as the main villain. He's the only one that can go toe to toe in combat, outsmart, and out strategize Batman. It should include the entirety of Gotham City (Before, I hated the idea of an open world--now, I want MORE!) and the whole Bat-Family should be involved.
I think the Arkham City premise was a bit of a rip-off of the "No Man's Land" storyline from the late 90's. In that story, Gotham was rocked by an earthquake, and a virus outbreak and the U.S. government basically said, "Fuck 'em." Gotham was cut off from the rest of the country and nobody was allowed to come in. And those that stayed in (including Gotham PD, and a few citizens that wanted to stay) weren't allowed to leave. In that storyline, the villains of Gotham divided up the city and marked their territory with "tags". By the time the story was over, Batman had taken out all of the villains and the whole city was Batman Territory (and Lex Luthor was behind the whole "Gotham is No Man's Land" thing).
I would LOVE to see that storyline made into a game. It would probably not be possible but still, one can dream!
