4. Bigger Bigger Bigger
Even though Arkham City was a much larger sandbox for Batman to glide around in than the Asylum, it can still be argued that as open world games go, Arkham City wasn't really as big as one would hope. Take a look at the Spider-Man games or Grand Theft Auto series to see how big a world is possible. Let's see Batman finally exist in a digital rendering of ALL of Gotham. I know how hard it must be to create such a world in a video game, but come on, doesn't Batman deserve a truly sprawling Gotham to protect? I want to dive off huge skyscrapers and stop petty crimes like robberies as well as crack the main storyline. Bigger world means more options in missions and navigation. Which leads to my final demand.
