I don't mind a reboot really. I didn't like the way AK ended, I'm quite happy with just making game after game with free roaming Gotham and fighting villains as Bruce Wayne.
If it’s WB Montreal doing a new game, them doing a “spiritual sequel series” would be a great way to make sure they have total freedom for story, character design, and style, show respect towards the Arkham Knight ending as being definitive for that series, and excuse for nah major format changes (free roam with multiple Batfamily members, etc) and give them more slack from any remaining Rocksteady loyalist fans who would always consider it an inferior entry because it wasn’t Rocksteady doing it.
*If* we’re fortunate enough to have them release some stuff online with E3 cancelled... I’d really like to see them do the implied “factions vs Batfamily” image as one, just so we can see who we might be playing as and playing against.
We’ve got four main slots in the center that intuitively would be Batman and his allies, with smaller circles next to them as well that could maybe be even more characters (maybe as resins) or just decorative. The top candidates I’d have for those characters is Batman, Nightwing, Batgirl, and Catwoman (keeping it even at two guys and two girls, each of whom could have a reskin alternative of some kind).
For bad guys factions...
Shown Symbols
Checkmate/Task Force X (Government Symbol with crossed swords and crown for chess motif) - Boss Battles with classic Suicide Squad members?
Demon/League of Assassins/League of Shadows (Creepy Demon Face) - Ninjas, Ra’s, Shiva, etc.
Pure Speculation for Other Slots
Court of Owls (Owl Symbol?) - This faction feels like it will inevitably appear at some point in a Batman game, and exceptionally durable and acrobatic henchmen and villains would be a unique gameplay challenge. Maybe Nightwing and Batman focused villains?
Leviathan (Skull?) - I’d just love to have Talia leading her own faction in opposition to Ra’s, and having the Heretic as a boss would be cool, particularly if Damian is a major hero.
Joker Gang (Clowns?) - I don’t feel if I need to explain this...
Bane Army (Bane Symbol?) - I love the Venom-fueled Mooks from Origins, and Bane having a faction always seems fitting.
Arkham Escapees (“A” Symbol?) - Again, just a classic setup of Arkham villains.
Falcone Mob (Rose?) - Classic mobsters, and one of two faction ideas I have for good villains to be victimized by Catwoman.
False Face Society (Black Mask?) - The other classic monster group that Catwoman could rob from.
