A Kickstarter update for Limit Theory introduces a new order-based market system being introduced to this upcoming procedurally generated space game (thanks JDreyer). The update includes this video diary explaining what this brings to the game. Here's a bit from the update:

A real, order-based market now lies at the heart of the economic activity in Limit Theory. With the ever-powerful principles of supply and demand realistically driving the prices of resources at markets, we now have a reactive, living economy in which the changes affected by you and NPCs alike will have resonating effects on the whole of the economic equilibrium. There is no smoke here, only reality. Ignore it if you choose, but know that in understanding and learning to shape the market lies an incredible amount of raw power. Don't let it go to your head >:]
