It might appear that way, but I didn't want to get into a full economic simulation [1]. That's when I decided to simplify the problem to just the money exchange (which is why I started with a random amount of money to be used). The seller is offering "something" the buyer wants and thus, the exchange of money. But hey, the outline of what I did is there---try your own hand at simulating this. [1] I thought of maybe food, materials and energy (ala M.U.L.E.) but I had no way to determine realistic price levels (or want levels for that matter).
