Is it possible to modify, say, ice terrain so that player can make city on it but AI cannot? I remember something like this was possible back in Civ2, but CIV4TerrainInfos.xml seems pretty straighforward and I cannot see anything that would make possible what I want to do?

No, you would need an SDK change to do that.

Too bad, coding really isn't my area of expertise..
Well, thanks for quick answer though :)

That would require making a new "variable", for example : aibuildable
and then adding it to said xml file?
