Thought you strategists might be interested in a new modpack that features deepwater ports. The idea is that big ships can only enter coastal cities that have deepwater ports. If a coastal city has no deepwater port, smaller ships can still enter, but not big ships. This feature adds a fun new element to Civ3. You can find it in a modpack called Age of Piracy, now available at http://civmods.com/aopdemo.htm
