This server is called EarthStonks and it is like a geopolitical economy simulator in Minecraft. You do not just build a house. You build a whole nation with money and debt and trade.
The world is an Earth style map where you fight over land and resources. There is Towny so people can make towns and nations. War is about profit and not just fighting for fun. When you conquer a town you get half of their important resources like oil iron and gold.
The money system is really serious. Nations can issue war bonds when they need cash. Other players can buy that debt to make money later. If a nation fails to pay back the debt the bank can liquidate their land and chunks get unclaimed so people can grab them.
Mining is also different. Normal ore generation is turned off to stop x ray cheats. Instead there are special real world resource zones. You go to those places and mine normal blocks and you get the rare resources that match that region.
Right now the server is in open beta and the economy is fresh and the map is mostly unclaimed. It is made for players who like strategy and money and long term planning. The server runs on Minecraft 1.21 and higher on Java.
