Is there a way I can make it so I can make farms, towns, mills, and such on desert terrains? I just wanna be able to make it so they can have more than just roads. Any help will be greatly appreciated.

It's a straightforward xml mod. Go into the Civ4ImprovementInfos.xml and add desert to the list of TerrainMakesValids for farm.

Is this thew way it should look? I added my change here in bold. This is from the file CIV4ImprovementInfos.xml, is this the only file I need to change?

that should be all.

I cant seem to get it to work, is this the only file I need to change? Is there anything Ineed to do to get the game to do this feature?

You need to change also :

- <PrereqNatureYields>
<iYield>1</iYield>
<iYield>0</iYield>
<iYield>0</iYield>
</PrereqNatureYields>

that actually require a minimum of 1 yield of food to be improved .
change to :

- <PrereqNatureYields>
<iYield>0</iYield>
<iYield>0</iYield>
<iYield>0</iYield>
</PrereqNatureYields>

you can try that , i don't know if it's enough .

tcho!

Thanks that did it!
