Here we have an example of relative value in tournament Offworld Trading Company FFA game. Player RainbowIdeology has had an elemental quarry mining silicon, and now has a modest stockpile built up. He could sell the silicon to the market for cash, but doing so would lower its market price. Opponent Rhahi’s two glass kilns, each of which consumes oxygen and silicon to produce glass. Since her kilns are using more silicon than she collects, she is forced to buy silicon off the market to run them. If RainbowIdeology were to depress the market price of silicon, Rhahi’s profit margins on glass production would grow. Instead of selling to the market, RainbowIdeology constructs three solar panels, each of which costs 100 silicon and 20 aluminum. The panels will (at least for now) be very profitable with the current high power price of $198. Rainbow got more value out of his silicon stockpile by building solar panels than he would have by selling it.
