Batman: Arkham Asylum was a breakthrough in gaming, mixing an intense free-flow combat system with solving puzzles and just generally kicking bad guy ass as the dark knight. Now if B: AA was good, Batman: Arkham City will be at least 50× better. Watching the trailer for it, they developers stated that back in B: AA E. Nigma aka The Riddler was pretty much a ghost on the sideline, you were aware of his presence through the riddler puzzles and challenges but he wasn't much of a threat, usually annoying. But in B: AC, there are around 400 puzzles you must solve, collect and figure out, so The Riddler is keeping you on your toes constantly. The Joker is back of course, with a darker, more evil attitude then previously, and now with this next installment we will be seeing the likes of The Penguin, Two Face, Cat Woman (and play as her for 10% of the game), Robin and even Calender Man apparently just to name a few.
I cannot wait for this game and will most likely nerd all over my floor the moment it arrives on my door step.
