SO you can only become part of one town/metropolis citizen at a time? But does that mean also that who ever sells gear or material in that town/metropolis sells it only to it's citizens? Like I can't go shop in another town if I'm not a citizen of that town or does that depend on the government type or rule? Or say I don't commit citizenship to any node, can I still buy stuff from players in shops and in different cities? Also, what are the benefits exactly to citizenship besides owning a house or freehold?
