your Proximitus, a hero who returned from america, and sailing back to england.. on the way, he founded a hide-out in the middle of a lake, you must help him defend itagainst evil pirates who want to capture it for themselves
Evil Pirates will only attack if they are created or populated during the game design.
You cannot depend on a civ advancing and building docks, ships, etc, on their own, you have to use triggers to achive this desired game play.
Giving your civ the advantage of imperial age and resources at the beginning of the game makes it too easy to eliminate the enemy, especially when they are just starting at the bottom of the ages. Surrounding your hide out with cliffs\, and only a tiny landing area makes it almost impossible for a defeat, especially when playing against the comp.
I suggest you make some changes and re submit if you want to boost the fun aspect of the game.
