In-game economy

• In-game money can be obtained through mining natural resources. These resources are rare

• Free market

• Physical delivery of items will absolutely be required

• Probably some sort of Uniswap-like AMM, running in different market hubs

• Property: no property rights coded into the game; whoever has de facto control over a piece of land "owns" it. Different states can define their own property rights & have their own property registries, enforced by their own police.
