Spice Road is now available from Aartform Games, offering a trade simulation based on the 18th century spice trade that made east/west relations of the time so darned spicy. A playable demo is available for your sampling pleasure, and they are also working a Greenlight campaign to establish trade relations with the nation of Steam. Here's word:

You are a colonial governor in the 18th Century, building a town on the Spice Road in a time of war and discovery. More than spice travels your roads - musket armies, philosophies, and power plays that span the globe are at your control. From palace to monastry, trade post to smugglers den - your town is worthless without the nobles, monks, merchants and rogues that chose to live in it - and keeping them all happy at the same time is never simple.
