Kalypso Media today announced the return on the Patrician series of strategy games. Due in Autumn 2010 on PC, Patrician IV is being developed by Gaming Minds Studios and is set during the late middle ages.

Starting from meagre beginnings as a small stall trader, players must use every skill at their disposal to rise through the merchant ranks and become the most powerful merchant in Europe. The authentic supply and demand-based trading system allows players to grow their business and head out to the high seas to form trading routes with other Hanseatic cities negotiating better prices for the buying and selling of goods.

Here's a short teaser trailer to go with the announcement.
