While the game feels like an expansion pack of Arkham City, the feeling of Batman is great. My issue with AO is the bugs and glitches on the game, everytime you fast travel or get a long cutscene there's frame rate issues; the way to play this game is the PC (even tough is still has plenty of issues).
Troy Baker does an amazing job as the Jokey and Craig Smith falls a little behind as Batman, he sounds more as Bale than Conroy.
I wish the DLC didn't involved re- skins of Batman but hey at least we got free skins: Knightfall, Adam West, Noel, One Million, Dark Knight, etc.
The story feels better that Arkham City but weaker than Asylum. Still I rather play Batman a game that no Batman game at all.
