My comment is rather negative in the sense that I think Batman lost his murky and oppressive side of Arkham Asylum promoting the open world. This side where we are told what "joke" would give us the wildcard at each corner of the corridor. The arrival of catwoman helps freshen the gameplay by playing more on agility compared to a batman who seems very rigid compared to her. The gameplay has not changed is still as nice as the soundtrack but it's really for me the side atmosphere that puts a notch below Arkham Asylum which remains for me the best batman for now on ps3.
