Just finished the game, and I must be one of the few that thoroughly enjoyed it. To be clear, I got all three Arkham games, and all three are collector's editions -- sweet spot for statues and Bats/Joker, so do the math.
Where I'm going is, although I have played and loved the previous two Arkham games, I have a question that I'm sure I'm too stupid to answer myself. Joker often hallucinates Batman as a monster. Is this ever justified/explained? Is it a nod to Man-Bat? Is it something deeper? Honestly, due to how I work with games, I can't stick too long with one, so after I beat the other two they went back into the collection shelf (although I plan to replay them now back-to-back). I can't remember if this was ever explained in the other two games, or even shown again.
And another question: we, at a point, "play" as Red Hood, the pre-Joker status of Joker. I'm pretty positive he hasn't appeared like that in the next games, but again, I could be wrong. Is there any more about it, or just a nod to fans? Does it mean that the writers followed The Killing Joke origin for Joker, or maybe just implemented his design from there?
Thanks in advance guys, fill me with knowledge!
