User blog comment:TheBAT21/What Years are Arkham Origins, Asylum, City, and Knight set in, and how do you know for certain????/@comment-25480373-20150730184501

Cellphones, texting, and upgraded computers didn't exist in the 80's. I think that Arkham Origins, Assault on Arkham, Arkham Asylum, Arkham City, and Arkham Knight took place in the 2000's or at least the late 90's.
