Port Royale 3

The highest rank is ‘Ruler of the Sea’ and can be reached with a total worth of 6 million gold, a holding capacity of 25,000 and 6000 total employees. This achievement will most likely come naturally as you progress through the game and work towards other achievements.

- 6 million gold will come with ease as you progress through the game expanding you trade routes and businesses, completing tasks, finding treasure, and attacking towns and pirate hideouts.

- To reach 25,000 capacity you will need to buy/capture additional ships and build multiple warehouses.

- 6000 employees will also come naturally as you progress through the game and work towards "Puppet Master."
