Batman

So I've been playing through all the Arkham games lately, and I had an interesting thought about the whole Arkhamverse as a storyline.

I think the entire game series is based (loosely) on The Killing Joke story, with other major events, references, and storylines lifted from other Batman comics. I just think TKJ was used as a basis for the games' world.

We see Joker's beginning with his flashback at the end of Arkham Origins, which is almost identical to his TKJ origin, as well as him crippling Barbara in that flashback during Arkham Knight (right down to the clothes he's wearing). The overall dark tone of the games lend to this theory, as well as Joker being shown just how sadistic he can be.

What do you think?
