Batman: Arkham City - 8/10
I know. Everything about AC is better than AA...except the main story, lame ending, final boss battle and overall eerie feeling. Some of my favorite things about AA were the Zelda like level qualities and the creepiness of the Scarecrow. Both are noticeably absent in AC.
Don't get me wrong, because this is still a really good game that I really did like. It's just that I liked AA more as it's one of my favorite games ever. If AA was a thriller, then AC is an action movie.
