The main thing about the CIV tiles is that the grass, sand, water, etc. are just one base pattern for said elements. The problem is how to call up the various things that decorate the base like mountains, rivers, forests, lakes, and commodities like cows, iron, pastures, etc. I have the pics from CIV 4 unPACked (a PAC file is sort of like a zip file) onto my pc in a folder that I look at often for ideas. If you want I could send any of this to you so that you could reference them for helping you think your way through the process. I also have the pics for the Fall from Heaven mods in all of its various forms and upgrades and the Beyond the Sword bonus pack. I have all of the past CIV games and bonus packs as well...huge fan can't ya tell
