That was awesome. The more I see, the more excited I get.
It makes me wonder, though, about this whole Gotham open world that these games have created. With all the characters in the Batman universe, both good guys and bad guys, there could potentially be an unlimited number of downloadable missions, like "Harley's Revenge" in Arkham City.
Based on what I'm seeing, it looks like WB is definitely respecting the earlier Arkham games. If this turns out to be a good game, I'd feel comfortable with them continuing the series instead of Rocksteady.
