If you want to keep up to date on Batman: Arkham related news, then this is the place to go. It has everything from official announcements, to rumors, to community discussions. It's a good site, and almost everyone knows each other.
Although the site has plenty of new news stories, it doesn't exactly stay up to speed on certain things. I find thousands of comic book news articles on comicbookmovie.com that contain new information that cannot be found on superherohype.com.
This site has the LARGEST selection of comic books you will ever see, be it in a store or online. The customer service is very well handled and the prices are outrageous! This is a site that all comic book fans need to visit at some point in their lives.
