Why isn't Batman: Arkham Origins part of the Batman: Arkham trilogy?

[†Diablo†]

It is also an Arkham game and tells the prequel to Batman: Arkham Asylum!

maybe someone can explain this to me.

I was happy when I saw that the Batman: Arkham trilogy was finally coming to the Nintendo Switch, but unfortunately I realized that Batman: Arkham Origins was missing.

IKR! I think that is stupid that it is separate from the series pack, plus it's only $5 by itself but the season pass is another$5 which is dumb because y don't they just include the season pass with the dam game instead of having them separate?? makes no sense

because people hate greatness & because rocksteady is salty that they could never get their own engine to make boss fights work which is why delusional shill city bandwagoners say mr freeze is a great "boss fight" ...a glorified stealth segment is considered the best boss fight, thats pathetic.

It's not considered part of the trilogy because it was made by a different company. Arkham Asylum, Arkham City, and Arkham Knight were all made by Rocksteady; Arkham Origins was made by WB Games Montreal.
