Yeah I know this has been brought up before, but i have a few sugestions that may help. One thing is trade. For every overseas trade route there should be a trade ship representing the trade between the two cities. To avoid micromanageing commerce The trade ships would be automaticly/instantly built in the city. Their speed would be 3 in the age of sail, but get faster after the discovery of combustion. There would be enough for one trade route so that one would arrive in port per turn. Example: Hamburg is trading wth New York. New York is 3 spaces away, so there would be 1 trade ship. Hamburg also trades with St. Petersburg which is 6 spaces away, so there would be 2 trade ships. During wartime these ships could be pillaged accoring to whatever the value of that trade route is. In addition there should be pirates and privateer units added to the game. privateers could be used to attack a foreign civs trade while they are at peace. they would be cheap and fast ships. However you would only be able to control them for a short period of time before they begin to attack everybodys trade. More Naval Units should be added to the game. The man of War and the sloop for the age of sail, And The cruiser and nuclear submarine for the Industrial/modern periods. Sea resources should not have to be in a nations culture borders to be accesed. A civilation should be able to sell some of its excess food to other civs. This transaction could be represented in the same trade ships used for trade routes. This way a civ can attempt to starve another civ into submission, like the way germany did to great britain in WWII. Naval units should be able to bombard land improvements. Also they should be able to attack land units in a similiar way that fighters do.
