Sea cities and improvements

[Indigo]

I miss not being able to build sea cities. And we can't build fisheries or nets to maximize the ocean productivity? Am I missing something here?

Harbors get an extra food from each sea square and offshore platforms get and extrra sheild from each sea square.

Woody is right but CTP is superior in this aspect. After all, in real life, a high percentage of the great cities of the world are ports and this won't happen in Civ3. Oh well, Civ3 is better in other aspects.
