My idea of a good city rp
Tier one
Workers can mine "plastic" from Bricks (needs food to be mined) Hunters can hunt for food which allows plastic to be mined Plastic is used as a currency
Tier Two
Plastic can be refined by a crafting gui or something like that ( crudly refined) Food can be cooked
Tier Three
Refined plastic
Used for Building, Job specific Events, etc used to build goverment buildings
Goverment system
Goverment runs via players, they choose their type of goverment (or some one comes into power and chooses it for them :D )
3 types of Goverment.... Monarchy, Democracy, and of course a goverment like USSR
