Broken poll is broken.
My favourite DC villain is Two-Face (mostly because of Jeph Loeb's 'The Long Halloween' and 'Dark Victory') so I'm really hoping he plays a major part in the game.
My favourite thing about the characters, so far, isn't actually the villains but the decision to bring in a playable Catwoman. I fucking love Catwoman and her relationship with Batman so their relationship within the game is gonna be one of my favourite parts of the story.
I also really like the look of The Riddler and his trailer looks mysterious and very intriguing.
Arkham City is definitely going to be my game of the year. I usually don't like saying shit like that before I've even played a game but I'm sure about this.
