Post in this thread terrain improvement suggestions for CIV IV. Here are a few of my suggestions:
- Offshore Oil Platform - This should be a terrain improvement instead of a city improvement. You can only build it on ocean squares which have oil as a resource, and it supplies oil to your cities through trade routes which can be broken or pillaged by enemies.
- Wildlife Preserve/National Park - You build this somewhere in an undeveloped area of your realm and connect it with a road to generate tourism which brings in money and makes some citizens happy. It is available with the Environmentalism tech.
- Mine field - Pretty obious what it is. You put minefields to defend key areas of your empire from invaders, but you yourself can move freely over them because you know where they are placed.
- Landfill - I don't know how the new pollution model would be, but I landfills could represent a good way to eliminate pollution, or at least take it out of your cities and put it out of sight.
- Forts/Fortresses - I propose that these be done more realistically then they are now. You can perhaps build improvements within them such as barracks, in fact maybe you can use forts to build your troops instead of cities?
- Colonies - I would like to see them redone. They should extend a zone of control and have a population, and should be able to grow into cities later on. Starting out you can only construct simple improvements and units there.
- Research Station - Can be constructed in the polar regions or on top of mountains/volcanoes or in the jungle and so on. They help with research.
