This is a geopolitical Earth server where towns fight and trade over real places on the map.
The big twist is that iron gold and diamonds only come from certain real life areas. Your town has to claim those zones if you want to mine them with open pit style mining and pull value out of the ground.
You can run player shops and sell what you mine. You also cannot legally grab every resource your town needs so you have to trade or make deals. As your town levels up it needs more kinds of resources for upkeep like iron early on then gold and even oil which is a custom drop in specific zones.
The economy gets wild since players can give loans to help each other start up. If you want war you can raise money with war bonds then lay siege to enemies to take resources and demand tribute. There is also a fully dynamic server shop so people can mess with prices and try to short the market.
