I am building a spaceship / planetary exploration game and need an economic system in the back. Economy and trading will be quite important. I would like to have multiple types of currency and trade goods floating around and basically a simulation of buyer/seller trading and am looking for a head start. ideally some kind of stock exchange with speculation possibilities: Buying and selling shares in certain corporations, including the players own base corporation. This is kind of a microgame within the game: essentially the players fly huge dreadnoughts and need a corporation behind them to provide a basic income for fuel/repairs etc. At the bare minimum, their corporation will generate a default amount of revenue - and then as they gain influence it will grow. At any time trading and market speculation could give short term boosts. The system needs to be resistant to abuse so most of the major trading movement will be script-driven and based on game events, with players able to affect it incrementally. Easy right? Are there any assets out there that can help provide a framework or backbone for this sort of economic system? Anyone with some experience can throw a few pointers? I've been looking at Econsim - which is a GitHub project based on this: https://pdfs.semanticscholar.org/e933/0d06ec6a830aa1dd2cd9e6bc38daa95db6dd.pdf Sadly it hasn't been updated in over 3 years and breaks my unity. I'm not a programmer so I kind of need assets to work out of the box. https://github.com/omikun/EconSim Did anyone get any ideas?
