All you idiots and your transliterated Boston accents make me want to cut out my ovaries and I ' m a guy . <| sep |> Well I don ' t mean to reign on your parade any harder but I don ' t think they are very useful either and I ' ll explain why . Unique districts are half the price and don ' t count against your limit . Neighborhoods already don ' t count against the limit so the mbanza looses out there . They are half the price but neighborhoods are already not that bad in price . Also a mbanza only really nets you 1 maybe 2 bonus housing over a neighborhood . At this stage of the game housing just isn ' t an issue anymore . If the mbanza came a little after aqueduct then it would be great but it doesn ' t . Mbanza is simply a better version of district but isn ' t optimized in Era . Certainly useful but I ' ll take Germany ' s hanza any day
