[@Blue Demon] Well, presumably this is a city-station, will a fully contained 'system' of sorts. So in addition to the stuff you provided: The main Hub Cargo Living Quarters (Presumably divided into wings, with various types of suites- small apartments, larger ones, full-size for the richest) The Bazaar (Market) Docking (presumably divided into multiple wings, for ships to dock on any side of the station) Dinning Area (Mess Halls/Restaurants) Command Deck There might also be: Manufacturing Water Treatment Life Support Deep Storage (Frozen, deeper within the station) Hydroponics Meattanks (we can 'grow' meat in a tank, yes) Waste Treatment Entertainment (parks, arcades, etc.) Enforcement (for the police of the station) Academy (for training of police, engineers, hydrofarmers, etc.) and more.
