The Game, Batman Arkham Asylum, though on an Island, was based in an open world structure. As such the style of gameplay lends itself well to it. But there is another element missing. Co-op campaign and Multiplayer. Since the New Batman takes place in Gotham, games like Mass Effect 2 and Red Dead Redemption, we see how structured an open world can be, and with games like, Splinter Cell Conviction, and a host of other multiplayer games, we see how bringing these two world together is the final word in gaming.
Since Batman AA uses the Old Animated series Voices, it is appropriate to deliver story missions as an "Episode" example: The Joker Episode, or, The Two Face Episode, each villain having a 2 hour mission.
As the game would be open world, the "episodes" would be specific story missions that can be completed in that world.
BATMAN NEEDS CO-OP and Mutiplayer! SIGN THIS PETITION TO SUPPORT CO-OP AND MULTIPLAYER!
Batman AA, though set on an Island, is an open world. This should translate to Gotham with Co-op Campaigns, and Multiplayer modes. Splinter Cell Conviction introduces Stealth Gameplay to traditional Co-op, and set in an OPEN WORLD, imagine.
The game just like the Animated series, would be broke down into "episodes" i.e, The Joker Episodes, Two face Episodes, ect. Just like GTA, it is an open world of everyday crime fighting, or you can do specific missions.
