Paul Dini is easily one of the best Batman writers you'll ever read. I can't help but think that his involvement has been a major contributing factor in the quality of Rocksteady's Batman: Arkham Asylum. Dini's another reason you should be paying attention to the comic series preceding Batman: Arkham City.
I'm probably a little biased. I grew up on Batman: The Animated Series.
The first issue of said comic series is available now and picks up immediately after Batman: Arkham Asylum. In fact, Batman: Arkham City Issue #1 overlaps with Arkham Asylum. The miniseries will spread across five parts with parts 2 and 3 in June and part 4 in July. Don't forget that Batman: Arkham City will be available on October 18th.
Rocksteady and WB Games will most likely have a huge showing for Batman at E3 2011. You can stick with Game Revolution for all the news, buzz, hands-on, impressions, trailers… phew! – and screenshots leading up to and through out the biggest show in gaming.
