Polynomics is an economics simulation game currently in early development. The game begins in a sparsely populated and untouched landmass where the player is tasked with founding a government and implementing policy. Each agent in the economy acts out of self interest, initially just trying to survive by gathering food and seeking shelter, but then evolving into having to make more complicated economic choices.
As a player you control the issuance of currency, how revenue is generated (through taxation policies and/or government owned entities) and how much is getting injected back into the economy (the cost of running departments and policies implemented by them).

An early access version will be released in early 2016.
Linux, Mac and Windows.
Yes! Part of development has included the creation of a custom asset editor and it will be released as an open source project sometime in the near future. This will allow basic modding such as adding custom buildings, cars, resources etc. A more extensive mod kit is being worked on but will be released sometime after alpha release.
For the initial release English will be the only supported language, but international support will come shortly after.
