I feel like I can say this: out of the Arkham Trilogy, I liked all the character designs except for Bane. Bane never really has a bad character design (even Batman and Robin's Bane LOOKED great), but I really disliked Arkham Trilogy Bane.
When you find out that Batman has a contingency for himself just in case he gets mind controlled or whatever, the idea that he thinks if he kills one person, it would break the mental barriers he placed on himself makes the no-kill rule look like more of a copout.
