One of my biggest regrets has been that once you finish all of the quests from a Neighbourhood Contact you never interact with that contact again. On the original DN1, they had full background and details about the various neighbourhoods, the exile gangs, the exile contacts and their relationships with each other. It added nice little nuggets to the story of MxO.
I'd love to see more quests added for each neighbourhood contact, and perhaps more interactivity between us redpills and the exile contacts.
