Gamers have long been begging for the Arkham entries to be Co-Op, and hopefully with this 3rd entry, we will get our wish. However, in addition to this, what's also needed is more downloadable content: more maps to explore, and new missions to finish. The entire Arkham series is rich with extra gameplay by way of The Riddler trophies and what they represent, and Arkham City even gave us a great new story with the addition of Harley's downloadable Revenge... but we need more. And odds are this time around, given the events of Arkham City, we aren't going to get any more Joker... so no more Harley is also a great possibility. Downloadable content and co-op gameplay are two great ways to make up for the Joker/Mark Hamill deficit, and they are long overdue for substantial involvement in this series of spectacular games.
