After reading the entire article, I gotta say that this entire feature is made of yummy nostalgia goodness that threatens to unravel the very fabric of the intarwebs lol
Now, if they can wait until next console cycle, then we can have an all Gotham City Batman game but as is now, that just is not possible.
Doing an all Gotham Batman game in this cycle will result in the game being in developmental hell for years because that idea is just not possible with even a 50-man team. Sure they can just make a generic Gotham but wouldn't you rather have a Gotham done with the same amount of detail and love like Arkham Asylum?
In all seriousness, great article!
