Has there been any discussion about making the seas more dangerous? Why are there never any barbarian ships? The game would improve from having barb ships attacking your coastal cities and water units and improvements. How about incorporating this into any or all of the ways barbs are created: randomly in fog, in barb cities, or improvements-- (there could be barb-only pirate coves that spawn dragon ships, or even pirates). I miss Sailor's Dirge, but even then it was just a matter of building two dragon ships to take her down if she came, and then there was no more use for your ships. Is this an issue in Civ4 too? I don't remember. Are there any mods that address this?
