Grand Voyage from NGames.
Set in the historically accurate 16th Century Mediterranean coast region, Grand Voyage is described as a late-Renaissance maritime trading MMO that lets you grow from small-time captain to legendary voyager in control of your own fleet. Since all trade prices change dynamically based on player actions, the economy allows for a stock-style way to buy low and sell high.
But rest assured, there is combat in Grand Voyage, and captains must keep their ships in top working condition while battling opponents across servers.
Grand Voyage is on the Game321.com online games portal, and you can follow them on Facebook or Twitter to find out more.
