The top choice on everybody's list was probably your top choice too. The Arkham series were the first to be game of the year caliber packages. Arkham Asylum understood Batman like no game before. It made you FEEL like you're Batman. At times you have to be a warrior. Sometimes a detective. You need the skills of a stealthy predator. Most importantly, you are a hero. They did a terrific job of putting Batman’s rogues gallery together too.
Arkham City expanded and actually managed improved on all of that. Because they gave Batman a city to stalk, they delivered the ultimate Batman experience. You can hunt criminals in alleys, find clues, and stop crimes. You are vengeance. You are the night. You are batman. Arkham City gave us the perfect Batman experience, and it had everything we could ever possibly need from a super hero title. From the opening with Bruce Wayne's capture to the jaw-dropping, joke-killing finale, Arkham City is, without a doubt, the greatest super hero title of all time.
