Initially, the trials and tribulations of 17th Century trade doesn't sound like fertile grounds for a naval strategy game, but a quick glance at history and Nitro Game's East India Company say otherwise.
East India Company is equal parts Civilization-style trading sim, RTS and shooter. After a short CGI introduction, East India Company gives you the opportunity to choose a country and begin your conquest of trade routes. Before getting into the actual mechanics of trade, understand that even though you are sailing under the banner of a country, you aren't actually playing as a country. It's a minor issue, but worth noting.
