From the article:
"If there is one thing that most superhero games neglect, it is the feel. I rarely feel like a superhero in any comic-book game. That’s why Batman: Arkham Asylum was such a pleasant surprise. With engaging combat, intuitive gadgets, and a plethora of references to Batman lore, Arkham Asylum made me feel like I was controlling Batman and not another generic video game character.
Arkham Asylum was a well-made Batman game that offered a lot. Its sequel, Batman: Arkham City, isn’t much different. However, that’s absolutely fine. I was left wanting more Batman at the end of the first game, and I got just that."
