You may have XP/Vista set up to hide file extensions. Civ4 makes a backup of CivilizationIV.ini to CivilizationIV.ini.bak, and if you have extensions hidden you'll see CivilizationIV and CivilizationIV.ini (the backup file). If this is the case, double-click the CivilizationIV one and edit that.
If not . . . I dunno.![]()
That got it- thanks much!
I agree it would be more realistic, and I'd bet that if you searched the mod forums you'd find one such mod. You could post a question there to get a wider audience as well. I don't know of any mods that do that, but I don't know very much about gameplay-altering mods.
