The photo mode for Gotham Knights just keeps on giving. I've only now started to engage with it more--actively brawling and hopping around is very fun--and damn, are there sights to see.
I respect the bits of storytelling jammed into Gotham Knights, from:
**pedestrian chatter (indeed, the flavorful lines you might have heard from gangsters in Arkham is largely with regular citizens of Gotham)
**in-character database entries (some posthumously from Bruce; others signed with the initials the Belfry Batfamily)
**personal gallery items and posters across different villain hideouts
**lots of unique buildings, billboards, and murals
It's scrappy and I dig it a ton!
