I played, loved and 100% completed Arkham Asylum on both 360 and PS3 (yes, it's that good - though not perfect) so you can imagine how much I was looking forward to Arkham City. Unfortunately, it hasn't lived up to my expectations. It seems like Rocksteady have sat down and gone over Arkham Asylum, picked out the bits that were praised and decided if they just do the same again - only in much greater quantities - then the sequel will be equally as good. That's simply not the case.
Instead of five or six types of enemies to fight, we now have nine or ten. Which is fine, but Rocksteady have made the new enemies only vulnerable to one of Batman's combat moves, so fights become an exercise in picking individuals out of a crowd and trying to remember what move works on what enemy. Instead of the Arkham Asylum's perfect number of Riddler trophies to find and map system that would reveal their approximate locations, we now have four hundred to find and a hint system that requires interrogation of certain enemies (which further complicates combat).
Add in infuriating boss fights, unnecessary Catwoman segments (if I want to play as Catwoman, I'll buy a Catwoman game), distinctly dodgy sexist dialogue, no fixing of the fuzzy targeting and pinwheeling camera in combat, far too many villains and an utterly ridiculous set of PS3 trophies and the whole game just seems to crumble under its own weight.
Don't get me wrong, there are times when Arkham City is absolutely excellent - gliding through the night sky as Batman is a high water mark - yet equally there are moments where it seems to actively hate you - is there really a need for the "gloat-cam" moments after you've died cheaply because you've failed to play the game exactly as Rocksteady intended?
If you haven't played it, I recommend getting Arkham Asylum instead. If you have and want more of the same, be prepared for Arkham City to be disappointing.
