Gotham Knights

I wonder if Gotham Knights had a development story akin to Redfall in how it was maybe intended to be a live service title but then, for whatever reason, pivoted away from it before release. Perhaps Warner Bros. as a publisher and/or the developer studio in Montreal decided it had no staying power. Or WB deemed the then-still-in-development and now recently-released Suicide Squad: Kill the Justice League more fitting as their title for Batman universe microtransactions.

Batman: Arkham Origins

Batman: Arkham Origins is the only one of the four main Batman: Arkham games not developed by Rocksteady. My theory (and apparently the official story as well) is that Rocksteady needed more than two years to develop the new features of Arkham Knight but Warner Bros. wanted a new Batman game out sooner. Thus WB put their Montreal studio to make Origins which often times feels like a rehashed Arkham City.
