Holy Cow Arkham Asylum!
I'm now about two hours into Arkham Asylum. This is as good or even better than Arkham City! I just got to go through one of the Scarecrow's nightmare sequences where you get to see the murder of Bruce Wayne's parents and it's done better than the movies! Wow, also you get to fight a few more of the more interesting villains in this one, namely Scarecrow himself, Killer Croc(you have to do a secret mission in Arkham City to access him, not in this one though!), and a much longer fight with Bane. Arkham City is still the better of the two for me, but as far as getting a Batman origin story, I love this so far! Damn.
