I want a historically accurate trading simulation set in the early modern period: I want a multitude of ever-changing regional hard, soft and bookkeeping currencies, also bills of exchange, individual units of measurement for each product, paying in kind, putting sth. on the cuff, installments, various per item or volume based taxations, tolls, tithes, tenure, social privileges, staple rights, scheduled trade fairs, regulated fixed prices, lot sales, return freight, regulated transportational services, craft and trading legislation, significance of saint days, city level legislation, guilds and other corporations, the very relevant concepts of honor, contemporary obligations of social responsibility, familial structures and needs for a network of professional connections, monasteries as large economical entities, etc. pp.

All tycoons I have played just reproduce a shallow version of our current concepts of money and trade and skin it with historical images without even trying to research the historical setting they're in. They add complexity in many other ways that don't focus on trade (i.e. combat).

No fighting. No leveling. No building. Just trade.
